555 Timer chip tutorial

[nikku9899372006]

u r such an mother f_ _ _er.....wasted my time..

u changed the circuit so many time

u dont know anything abt electronics....

[TheCaptFrank]

WOW one KILI ohm???

[Gr3mI1n]

painful

[lansdowne42]

such a waste of time, i have learned nothing.

[a2zhandi]

@lansdowne42 look in the mirror and see stupid.

[nurdsmart]

you need to learn a lot before posting yourself

[nurdsmart]

micro farad get it right

[vysakhk]

its not UF its 'mu F'

[sw204me]

who makes a how to video that doesn't care about helping people?

[marc1979Guitare]

Thank you so much you save my life :) I finally understand after 5 hours of work! :))

[ndonionapoli]

l'integrato che collega a 4.40 come si chiama??? ma a posto di quello potrebbe andare anche un led?

[xDfakboy]

Whit this you can do an emp right

[maqsoodu23]

ahhhh!!! dont touch the pins with bare hands..wear a non-static gloves or use an anit-magnetic tweezers!!! I hate it when beginners do this!!!

Please I know you are trying to learn electronics and are enjoying ur school (i am using ur going to a uni or college) but take the time to learn the basics first!

[stavnir91]

micro farad not UF -_-

[expertmax1]

@stavnir91 microfarad IS μF ! In circumstances in which only the Latin alphabet is available, the prefix can be represented using the letter u.

[stavnir91]

@expertmax1 True but you also said UF instead of micro farad.

Never mind..

[expertmax1]

@stavnir91 I never said "UF"... I think you need glasses 8D. Sorry man but I just hate it when people think they know everything ! I don't know everything, i copied it from Wikipedia.

[stavnir91]

@expertmax1 Sorry I didn't notice you aren't the creator of this video. He says UF @ 0:35.

[MrTipsytaxy]

I knew this guy didn't know wtf he was doing when he says u F for the capacitor...its called Farads you dumbass

your making a 555 timer chip? i dont think so

your using a 555 timer your demonstrating how it works even at that your only showing one demonstration on how to use it

[MasterEmeraldPhoenix]

what do u mean by ground output positive and nagative beacause my breadboard u determine which is what and i dont understand how to do that plz help

[dmd70621]

know your shit before you try to make vids

[liamshaw666]

Hello,

For an electronic project I want an LED to turn on, but when it turns on, I want it to fade smoothly on and fade out when it turns off, can I use a 555 timer using PWM to do this effect?

Thanks

[devinmccloud]

BlanchProductions , That was hilarious!

[computerfreaq17]

Can you use a POT or a Photoresistor? I'm kinda a amateur, XD

[dextapoul]

give him a break. we have all been amateur : )

[mondays89]

That totally reminds me of my alarm clock.

[HybridWaterMan2]

Nice and simple explanation- thanks!

[MrJouleJr]

...too pin seven, which is right next to left :P LOL

[gamccoy]

Sorry for the negativity in these posts. Keep at it. I applaud your curiosity. May I recommend learning and using microcontrollers in the future? You'll get to make some stellar projects with little hardware.

[Landotter1]

A 100 yoo ef capacitor? How about Micro Farad? How can you think that you are teaching anybody if you don't use proper terminology, hell, you don't even know the resistor color code.... I guess you don't feel like that either. I hate all of the catch words being used on YouTube but I think I will break my own rules here. This is an absolute, worst EVER epic, Chuck Norris, FAIL I have seen to date. You didn't teach anything about how the 555 works, dumb-ass.

[tonyrueb]

i get the feeling that you really dont know what your doing...

[gaussman08]

fafafa timer chip

[janagyjr1978]

Worst tut ever. Sorry buddy.

[AlienRelics]

This isn't a tutorial. You've said nothing about how a 555 timer operates.

[curlyhair2177]

its not uf its microfarot

[cappydawg]

@curlyhair2177 lol not hating, but you might as well tell him the right thing instead of confusing him even further. it's microfarad

[Landotter1]

@curlyhair2177 Hey, give him a break, at least he got the big word "capacitor" right.... haaaaaaaaaaaaa

[sd2787]

twat

[58belvedere]

real how to read the color bands on a resistor

b,b,r,o,y,s,b,v,g,,w < hint?

[z0tx]

This is a 100... I don't know actually

[mrmatt2525able]

made this, twice, doesent work worth fuck, thank for wasteing my time assmouth

[fellaz4sho]

you didnt say how you came up with that big silver capasitor and did you run a wire between pin 2 and 6

[SilverFox2018]

NEVER Put a wire diagonal. Always in straight lines it looks neater and is easier to trace

[interplexer]

Doubles get.

[interplexer]

Rollin........................­.....

[Thisisnotmyrealname8]

Is the pause in the noise when the capacitor is charged and then dissipates (the circuit restarting when it dissipates)? The ringing when it is charging?

[BlackSoulOfHeaven]

uuhhh just so you'd know, that letter before the F (farad) on the capacitor is Greek "micro" no English "u"

[Cds56]

I just ordered my breadboard, my fafafa timer chips (2 of them :D) and my piezo thingy buzzer, so now I can do this! I also ordered battery clips, which would be useful.

hhahhaha thumps up i you found his voice more funny than this project fafafafafafafa

wtf!!!! making a project without knowing resistor color codes what a yuck!!!!!!!!!!

[happygamestvfun1]

stop sniffing and chewing its extreamly rude and descusting

[happygamestvfun1]

"genttle insert into boad" *pruduces hammmer* *BANG BANG* "go on get in their you dirty fucken paddle stck"

[thatAIDANguy]

100 micro faroud lol

[happygamestvfun1]

how do i make my own 555 chip?

[DrMotorDude]

@happygamestvfun1 Seriously? You'll need a ~$500,000.00 worth of equipment. Then you'll need to learn how to do circuit deposition on silicon chips.

BUT if you go to a local electronic component supplier (I think Radio Shack still sells them) they only cost a few dollars. I got a 955 (555 for specific temperature ranges) for $2.00.

[happygamestvfun1]

@DrMotorDude OMFG ell oww elll, I don't mean make an actual miniture IC CHIP i mean make a PCB scale circuit that has the same logic as an 555 timmer chip.

[dieselscience]

@happygamestvfun1 I think there is a schematic of it on wiki...

[happygamestvfun1]

@dieselscience i dont know wwere to stick my schamtic tho...

[dieselscience]

@happygamestvfun1 What do you mean "stick" your schematic? You mean put it together based on the drawing?

[aruziel14]

the parts suddenly changed at 5:10 . . .

[ELPISON1000]

SILENCE!!!!!! I'LL KILL YOU!!!!!!!!!!!!!

[gamma526]

its pronounced pee-ay-zoh

[yesnobabu]

hey goody its OHM not YOHM

[pat3663373]

Terrible.

"u" Farad...?

It's called a microfarad.

I don't know the reisitance...?

That's what color coded bands are for. Should be able to look at it and know exact reisistance, with tolerance, in 2 seconds.

[Nadrealis]

@pat3663373 I'm studying for electrical engineering and I can't tell within 2 seconds. I usually have a little cheat sheet next to me but yeah I figure within a few months of working with the stuff everyday I'll be able to know off the top of my head. Yeah, this video is really bad.

[pat3663373]

@Nadrealis

That's where you learn, when you're studying.

I wasn't keen with the color codes when I started, but with time you'll know them by heart.

But A "u" farad.... that's bad!

[Accumulator1]

After 90 sec into this nerve racking video I was looking in the yellow pages for a mental institution to check into. The first two minutes were worthless and could be eliminated. The fumblinb around with component closups were so out of focus and the jabber...Ugh! A 1 min segment could have displayed a schematic, run thru the installation, demos and be done with it. Also the bread board needs to be up close to see the installation better. God I can't belive I wasted so many min of my life!

[bobflyman]

It's called a 100 micro farad capacitor not 1100 uF?

[Lotarionesco]

well...I'm new in this...but this tutorial just confuse me

[luxfero666]

............First 555 should operat 555 5 V ....... -.- read datasheet

............Second yo don´t need a buzzer to test it ............led only cost arround 0.12 dollars ( currency may be wrong but is 0.1 € or lower if yo get in packs)

............Third + - lines should never be used as outputs

...........For eletronics always use 7805 is a voltage regulater turn 7-12 V to 5 V( 5V will never change regardless off input) some devices may not work properly if you use batterys

[davidjereb]

@luxfero666 You have absolutely no knowledge of electronics whatsoever.

1. Most 555 chips tolerate more than 15V supply voltage.

2. You won't see a LED flicker at 10kHz. It will just be lit the whole time. A buzzer on the other hand will output a high pitched tone.

3. It's not good practice to use power rails as output, but who cares.

4. 7805 is in fact one of the worst voltage sources. If you are converting 9V to 5V, you are just throwing away 44% of the energy. A switcher should be used.

[YeahYeahYeahs8]

@davidjereb I think this setup produces about 1-2 Hz, not 10 kHz. You can hear the buzzer signal pulse. So actually you could use a LED. The buzzer gives its 10 kHz without any pulse signal, you just connect it to a power source. So as a result of a pulsing power source, which is 555's output, you get this pulsing 10kHz signal. : )

[emil057]

fa fa fa fa

[McZxjmonkey]

haha ur phone sounds like its out of power :)

[jake555timer]

i all ways look up 555 timer vids and i hook it up like they say and it doesnt work or they dont say were some lead goes.

[impavenleizar]

asshole

[xpzwhisper]

100uf capacitor lol...

100 microfarad rather :P

555 timer doesn't give you much of idea what goes on inside..

you're not really explaining why you are connecting it just this way ;)

you just have to connect this pin to that other pin to that and this is the result.

I would recommend using a relaxation oscillator and a bit of combinational logic to achieve this because there you know exactly what happens inside of your system and it's more challenging and a lot more ICs is needed :D

[msinclair810]

Poor inconsistent production

[OnllySkills]

thank you! you helped me SO MUCH. i have to do this for school and ur vid made my circuit work!!! *Like*

[x01000101x]

heh... "take that... take it .. gently insert it" 1:56 funny. Anyhow good video it's helpful to those who may want to get into hobby electronics but may worry that it has to be extremely technical all the time. It's laid back I like it it works in the end. I hear a battery dying at 3:09 on a cellphone too is it yours? lol

[panzuman]

whats the difference between an ne555 and a ks555?

[firedude201234]

@panzuman

whats the diffrence between a ne555 ks555 and cmos555 because ive got a cmos555 lol

[panzuman]

@firedude201234 as it would turn out they are all the SAME! its just the company that makes it ne was the first

[firedude201234]

@panzuman

oh thanks lol

by the way dont worry about voltage / input power @mustangman66

i run mine (powering a single led) with a power supply from my ps2 that puts out 8.5 volts at 5.65 amps or 40.8 watts

[Darkorbitrulz]

i made this in the beginning....

you don't need the capacitor between pins 1 and 5. just take it out and it works

[AxelTiger]

uF = microfarad, what a capacitors 'capacitance' is measured in.

[spudinator1]

not if your making a rail-gun lol

[AxelTiger]

well yes even if youir makiing a rain gun/ coil gun, you need individial capacitors to make 1 larger bank of caps, THEN you might need a higher rating level. I think the last largest capacitor was the arc of the covnent (reseach arc lights) lol

[SKMatoBB]

this tutorial dont works you said the pin 2 is pin 7 and 7 = 2 ????????

[firedude201234]

or maybe you have yours backwards dumbass!!!!!!!!!!!

[SKMatoBB]

oh my god youre right

[firedude201234]

sarcasm or serious?

[SKMatoBB]

serious

[firedude201234]

lmao!!!!!!

[intensenex]

i was jus making my 555 timer to work and runnin a 1.5v motor and the my voltage source is 9v with 300mA but i don't see my motor pulsating. Can someone tell me if i burned up my 555 timer IC?

[broncocv]

mmm, but how u did ur circuit???

[broncocv]

try making another circuit for ur timer and test it LOL!

[gmcjetpilot]

Radio Shack sold a project book on 555 timer. I highly recommend it. Google 555 timer projects. That IC chip can do a lot of cool things.

[broncocv]

that[s right!

[heading7593]

100 micro farads would be your uf that is the capacitance, and im suprised you don't know how to read color code. and the cap and the resistor is what gives you you frequency or as we call it "time constants"

[danimal511]

WATCH OUT 4 THOSE KILLYOHMS

[BlanchProductions]

At 2:33...thats what she said

[curlyhair2177]

@BlanchProductions no offense , but that sounds like a sex offender....**awkward silence** JUST KIDDING

[marocon60]

@BlanchProductions 2:32 dingus head

[supersanchez1991]

iif i want to add a switch to turn off and on where would i put it?

[Agent766]

Vin (Voltage in)

[gogogoligorsky]

@supersanchez1991 You could put the switch between your 9V battery's positive terminal and the red wire that goes to your breadboard. The switch will just open and close this circuit.

[PigsCanFly99]

What YOU want to do is draw a fool circuit diagram .. demonstartion fail .. I'm sorry this gets a big fat fail. Useless and ultimately infantile. Shitty is probably an apt adjective.

[9860798607]

yes i think so to

[wolveshockey1993]

I'm planning on connecting the 2 leads of the b button with a 555 so it rapidly presses it but a 360 controller only has 3v supply. Any ideas

[dblcltch20]

use a operational amp as a comparator, the supply volts should be about two more than what your looking for because the saturation voltage will be +/- 2v of your supply. Remember that a comparator has no feed back loop.

[Antipwnsurmum]

transistor or a relay, depending on how fast you want to make it go.

[Calloween1]

can i use a 1,5 m resistor

[IamTheMaxXx]

555 is a prehistoric IC man.

[unicyclst]

true.... but its cheap and it works

[lenny7494]

Did you know that more than a billion are still made EVERY YEAR?! So, it might be prehistoric in the IC & EC world, made in 1970, but it's still a nifty little creation and has as many uses as finger.

[DrMotorDude]

YET it is still in every NEW LCD/Plasma digital television.

[daredadevil]

that silver thing is capacitor i guess...... he mighta changed it....

[Cobalt961]

when you say all we need to do now is connect the battery, at the point the breadboard hasn't got that silver thing on the board which we see later just after you connect the battery! Why didn't you show what that silver thing is and why is it not in your description? What is it?

Awesome video, thanks for uploading!!!

[KrisPizer]

The "silver thing" is a capacitor the original cap may have failed when he tested it for the video so he swapped it out with that one.

[jms61239]

can you read color code? lol

[haseeb112]

can you tell me where you got the parts from?

[PaulTheElite]

A Fafafa timer chip

[Kleinalrik]

LOL!

[turf7227]

i want to make it adjustable with a potentioneter. where do i put the potentiometer?

[RobGatzke]

There's sooo many types of 555's out there. Does it matter what type of 555 you use?

[westkan]

There may be many MANUFACTURERS of 555 IC, but as long as 555 is printed on the package, the internal circuitry is the same.

[supersanchez1991]

how do you know what capacitor to use?

[killmore589]

It sets how often it will beeb, or do what ever you have it hooked up to. I belive it is how long it takes to charge, and then again how long it takes to discharge across a resistor. So a bigger capacitor gives you a longer time between the beeps.

[westkan]

Download a data sheet for the 555. They will tell you how to calculate component values.

[juniortore]

should put a speaker in there, whats the voltage of the capacitor?

[crazybeavers155]

gate switch what if its for a 12 v strobe

[crazybeavers155]

can this connected to a xneon strobe

[gaussman08]

this project we gonna make a fafafa timer chip xdd

[victormartinezu]

XD lol....

[IIIDarkWorlDIII]

@gaussman08 hahahhahaha im rolling

[talada2]

your verizon wireless RAZR phone's battery is dying @ 3:09 LOL! FAIL. You should build a circuit to send a packet over TCP/IP telling you your phone's battery level from any computer using a portable API.

[paulhunt]

who the fuck showed you how to mount resistors??

[494c6f7665416c6578]

I think that it is nice that he posted this quick video, but it was rather inconsistent.

He didn't explain the different standard operating modes, nor the equations for the various passives used.

He made clarity issues that could have easily been corrected in editing; like calling a resistor a strip, not knowing EIA colour-codes, the whole microfarad thing, and randomly switching his wiring layout.

Regardless, a entertaining video at the least. I hope he continues his study of electronics.

[carrotorangeshake]

so as not to create a misunderstanding, it's called microfarad, not a "UF" chip. this is the symbol--> (μF)

hope this helps :)

[JadenYugiGX]

this is my first year. and our project is to create a digital clock based on the 555 timer oscillations, by adding 74LS90 (counter), 74LS47 (Decoder), 7-Seg displays, lots of resistors, some logic gates.... It's done!!! although it's a bit confusing when it comes to reality!!!! :)

[JadenYugiGX]

The pin 4 SHOULD be connected to the 8 (actually to +V since 8 is connected there), pin 4 is the "Reset pin", it's active-low (means that the pin works when it's 0V) so when you do not connect it to +V, letting it free's like connecting it to 0V. thus, the pin 4 resets the 555 timer and makes it stop!!

[PyroGuideToHappiness]

so you can add a normally open momentary switch between the pin 4 and the +V and itl reset when pushed?

[494c6f7665416c6578]

No, you connect the switch from R (pin 4 or 10 for second reset on 556) to 0V(ground). Then upon pushing the switch the timer will reset.

You can also place a capacitor where the switch would be to create a power-on reset, which is useful in monostable operation.

In both cases it is good practice to place a resistor from V+ to the reset pin in conjunction with a switch or capacitor. This facilitates sourcing, rather than floating the pin when it is not active to insure it remains inactive.

[POSTgoodVideos]

Wow , I made in one trial, thanks very nice vdo

[nycpntr]

mine doesn't work unless pin 4 is connected to pin 8

[CertifyThis]

this vid was just fien bro. Those other guys just want to give you a hard time over the way you wired it up then let em, if they dont like it they can do a vid themselves. I dont like negartive comments on vids, an opinion is fine but dont rag on a persons vid NICE VID !!!

[fogglee]

no offence but you make breadboad circuits the most complex way i can think of

why not pin 3 to the speaker and speaker to ground just like that

and you just have to buy a battery clip to the outside rails of the breadboard

and then you can have power where ever you want

do you even know have a breadboard is wired

[videosrock654]

its not "uF" its "micro farad"

[cooperpk]

uF, is short term for micro farad =/

[TXzeroC]

LOL.... ur like "i dont know the resistance of the resistor" Just use the color code (or course, if you know it) Kool VID THOUGH!!! =]

[titanguitarman]

Why not use a pot for the resistance so then you can variate it.

[IIIDarkWorlDIII]

@titanguitarman thats how its done mostly yea

[Logo3801]

@titanguitarman ahah!!! thats what i thought? wait what the? why aint he using a pot? lol I used one it works great!

[arg13415]

also a 9V battery is almost never 9V supplied. I think they spend most of their life around 6 or 7 V

[titanguitarman]

When you get 9v the are range above 9v for consumer use. Resistors take the value down

[mustangman66]

you lost me...

never connect a 9 volt battery

absoulute maimums:

supply voltage: 18v (normal operation voltage: 4.5 - 16V)

correct me if im wrong but 9V is in between 4.5V and 16V...

[firedude201234]

@mustangman66

dont worry about it ....i run mine (powering a single led) with a powersupply from my ps2 that puts out 8.5 volts at 5.65 amps

[firedude201234]

@mustangman66

@mustangman66

dont worry about it ....i run mine (powering a single led) with a power supply from my ps2 that puts out 8.5 volts at 5.65 amps or 40.8 watts

[iBO0M]

idk wuts wrong with you guys this guy did just fine.

[sciencoking]

brown black orange gold is 10k ohm

red red yellow gold is 220k ohm

(these are at least the resistors i use)

[skierplaterandy]

uhh no, buy 1 and look i have 1 here and it says " absoulute maimums:

supply voltage: 18v (normal operation voltage: 4.5 - 16V) 600mW 200mA

-4F to 158f

(20c 70c)

[egn2020]

wow the kid changed the pot and told no one and he was kind of lost me a bit when he was explaning how to hook up the circuit.

[mustangman66]

then why, may i ask, did everything work PERFECTLY? and why does it still work perfectly??? seriously... get a life.

[IIIDarkWorlDIII]

@mustangman66 cause this is fuckin youtube and you are making ssuuucchhh an easy project that half of the wievers of this vid can make better and more complicated projects mate, they have a life.

[howisdiscool]

he never said he was going to make a 555 timer chip

[bo]

it's MICRO Farads. not UF, not MEGA :)
