How to make a 555 timer flasher

[engrmedina]

the LED didn't blink. But I did follow every step.

[1kuhny]

why deosnt anyone do 556 timer chip

[chipperdoda]

I did this!! It blinks, but not very fast!

[somerandomutewb]

@chipperdoda change capacitor or resisters

[209hii]

"uf" isnt "uf" its actually µF which stands for microfarad

[Flea5000000000]

@209hii

That is just fabulous. I have been told that about 6 times on this comment page, so IDK. I do know it means that, I filmed it 2 years ago when I was 12. ok!

[stalker7d7]

@Flea5000000000 miiiiiiiiiiiiicro fair add... lol

[Chehimi3Videos]

@209hii Dude, lots of people don't know the Alt-Key for that.

[209hii]

@Chehimi3Videos neither do i... but i think, and i went and copied and pasted it from somewhere lol

[Chehimi3Videos]

@209hii whatever uf is still fine it's almost the same.

[Kafrotox]

Nice work Flea, Thanx

[marc1979Guitare]

Resistor 1 - This resistor has to be a smaller ohm amount than resistor 2.(Ex-10k)

Resistor 2 - This resistor has to be a smaller ohm amount than resistor 1. (Ex-100k)

Resistor 3 - This resistor lowers the power before it feeds the L.E.D..(Ex-360ohm)

Capacitor 1 - The capacitor controls the pulse rate of the 555ic (Resistors 1 and 2 effect the pulse rate aswell).(Ex-10uf)

and in your video you said 10 k capacitor and 100k capacitor, is it the resistor or capacitor?

thank you!

[Flea5000000000]

@marc1979Guitare

Resistor2 - This resistor should have a larger ohm amount than resistor 1

When I said 10k capacitor I ment to say resistor as explaned in the annonations

[aNASTYfeed]

<GOD i love electronik!

Thats why im studding to an Elektrishen (HOW you now spell it.. HELP ME SPELL :D)

[cmor2125]

Where do you purchase your parts?

[Flea5000000000]

@cmor2125 allelectrionicsdotcom, robotshopdotcom, the source, radio shack, & digikeydotcom

[jobard69]

buy a new camera or learn how to use it

[Flea5000000000]

@jobard69 I did buy a new camera and I was 10 when this was filmed

[TheBK117B2]

thanks both circuits work nice

[nicolaselgato]

why don't you try making the transistor circuit?

[MasterEmeraldPhoenix]

Ok I understand thx

[MasterEmeraldPhoenix]

ok flea hi again i need help with a term i finally got it working thank you i did not just understand i am very sorry for wasting your time but what does 555 mean in a 555 IC timer chip and what does a 555 timer do for electronics plz help thx you

[Flea5000000000]

@MasterEmeraldPhoenix 555 is just the name of the chip. A 555 timer is used to generate frequancys.

[LolTechTutorials]

@Flea5000000000 Oh seriously? Lol I though it counted 555 milliseconds. Herpderp I guess that's why I'm watching this.

[theemusic92]

All my wiring is correct but my LED refuses to fucking oscillate but instead glows for a second & then dims.

[MasterEmeraldPhoenix]

Just send it to my YouTube they r the same

[Flea5000000000]

@MasterEmeraldPhoenix ok wtever I'll just put it on my channel

[MasterEmeraldPhoenix]

hey flea i am so sorry i still dont understand so i have to do something with a 330 resistor and put it infront of an LED and i dont understand can u make a video responce showing me plz i not trying to waste your time but i just dont understand

[Flea5000000000]

@MasterEmeraldPhoenix What is your e-mail? I'll send a schmattic to you.

[MasterEmeraldPhoenix]

how do i put it infront of the LED

[MasterEmeraldPhoenix]

no not yet so instead of 10k and 100k resistors use 330 resistors

[Flea5000000000]

@MasterEmeraldPhoenix no,no,no,no,no,no,no. KEEP THE 100K AND THE 10K DO NOT MOVE THEM. PUT A 330 OHM RESISTOR INFRONT OF THE LED SO IT WILL NOT BURN OUT!

[Flea5000000000]

@Flea5000000000

negative<-------led<-----330oh­m<-------555ic output



[MasterEmeraldPhoenix]

ok i am sorry if i am making u made i a noob but i need 3 vools and i dont have a 3 volt battery so now what can u make video response showing how to do it with 3 volt or something cause i just used 9 volt and i did blow it i confused and i dont have more powerful it like dimed then went out and now wont come back on

[Flea5000000000]

@MasterEmeraldPhoenix did you put the 330ohm resistor infront of the led?

[MasterEmeraldPhoenix]

OK THENKS I KNOW WHAT U MEAN BUT NOW I JUST NEED OT KNOW THE RESISTORES U USE SORRY ALL IN CAPS

[MasterEmeraldPhoenix]

WHAT TYPE OF RESISTORS DID YOU USE TO TAKE OFF POWER FROM THE 9 VOLT

[Flea5000000000]

@MasterEmeraldPhoenix YOU DON'T NEED THE RESISTORS, JUST MAKE SURE YOUR LED WON'T BLOW. IF IT IS LOW POWER LED THEN PUT A 330OHM RESISTOR INFRONT OF IT.

[MasterEmeraldPhoenix]

flea can u help me mine did not work i think beacuse my bread board does not tell which side is positive or negative can u help me lol again and idk if i am puttin the peices in the right spot on the board

[Flea5000000000]

@MasterEmeraldPhoenix It dose not matter if the bread board does not have labels, just connect posotive to the positive parts on the 555 and negative to the negative parts.Play around with the components and I am sure you will get it working. Allso make sure your capacitor or the 555ic is not backwards.

[MasterEmeraldPhoenix]

can someone plz answer me plz i need help what does everyone mean by 10k resistor and 100k resistor beacuse no one i know knows what that is can some one explain what a k is or gie me a link plz help

[Flea5000000000]

@MasterEmeraldPhoenix

10k = 10,000ohm resistor  100k = 100,000ohm resistor

[Flea5000000000]

@MasterEmeraldPhoenix It's just short for thousands.

[starwars2078]

Great video, I loved it! I know this video is from a while ago, but I want you to make more! By the way does one of your parents work at an electronics store, because you have a lot of parts!

[Flea5000000000]

@starwars2078 No, I am the only one in my family that does electrionics so I just order them off the internet and thanks. (:

[starwars2078]

@Flea5000000000 Where did you get all of them? Also I loved the project idea, it made me think of adding these to my bedroom door on a sign.

[Flea5000000000]

@starwars2078 Check out some my other projects on my channel. I got my components from- digikey, allelectrionics, robot shop, and The source. You can buy capacitors, resistors, LEDs, transistors in packets of random colours/amounts/NPN-PNP.

[Skyscraper446]

If I wanted to use this on a fire alarm buzzer (24V) it wouldn't matter what voltage, right?

[Flea5000000000]

@Skyscraper446 The 555timer can only use 5v-16v. IF YOU USE 24V IT WILL BREAK/EXPLODE. You can use a fire alarm buzzer by putting a relay on the output of the 555ic.

[Skyscraper446]

@Flea5000000000 Alright. Thanks for the info! -subscribes-

[Skyscraper446]

@Flea5000000000 Actually, one more question. For this type of circuit I would just use a 9V battery or some other type of 12V source, and change the output to close the relay, and just use the other 24V circuit to the alarms on the relay output? Thanks again!

[Flea5000000000]

@Skyscraper446 yes

9v->555ic->relay in->connect 24v to relay->output-> fire alarm

[acido08]

heyy,,, It's not Working.....why????

[Flea5000000000]

@acido08 more info to decide a solution

[wjz10595]

In theory if I used 10 LED's could I use a 220uF capacitor? I dont have a 2.2 and would like to knowif this is accomplishable.

[Flea5000000000]

@wjz10595 you can use a 1000uf capacitor if you want, it will just flash slower. You can change the speed by changing the resistors as well. You can use alot of leds on a parrallel circuit hooked up on the output, it will not effect the flashing speed unless you change the power.

[wjz10595]

@Flea5000000000 Okay thanks.

[99ELEKTRONIK]

spoko jest to

[balloonpoop]

So by using this method, is it possible to make an led setup so that you have a row of maybe 5 lights and the light goes down the line one by one? kinda like one of the sequences from Guy-Manuels helmet in Daft Punk?

[Flea5000000000]

@balloonpoop Hey, check out my other video on "How to use a 555ic with a 4017ic". This shows you how to do that.

[midrange18]

You seem very straight forward with your how toos. Do you have a vid for making 4 way traffic lights. 4 red while 4 are green kinda idea. of course with yellow amberbefore the red.

[Flea5000000000]

@midrange18 Ok I'll do a video on how to make traffic lights.

[midrange18]

@Flea5000000000  Cheers!

[midrange18]

Excellent. Today is the first time i have looked into making 555 circuits. This vid is the firstvid that actually made sence to me. I am curious though, i'll be getting my power from a 12V source (train pack) and all vids i have watched, all have used 9v battery.. what do I do to use the 12v coming from my power pack.

[Flea5000000000]

@midrange18 You can put resistors infront of the 12v or you can use a regulator

[merq100]

i cant see shit

[Flea5000000000]

@merq100 probably because I did not crap on the floor

[ludwigdrummer0666]

Where do you get your 555 timers from, I want to know where I can getva lot of them cheap.

[Flea5000000000]

@ludwigdrummer0666 Hey here is a site that sells the 555timer ics for 75c each----

[ludwigdrummer0666]

@Flea5000000000 theres no link :(

[Flea5000000000]

@ludwigdrummer0666 O it didn't post look on your channel I posted it there

[ludwigdrummer0666]

@ludwigdrummer0666 thanks

[Kpilot786457]

its not uf, its Mf., for microfarads. learn it or lose the hobby!

[Flea5000000000]

@Kpilot786457 (: I know now. I am teaching my self at home so sorry for the mistakes

[Kpilot786457]

@Flea5000000000 *wink* ya sorry for being so harsh!

[aldeed]

@Flea5000000000 IT IS UF!!!!!

UF = MICRO FARADS - its just how the capacitors are labelled. kpilot is a dick

[Flea5000000000]

@aldeed ok

[aldeed]

@Flea5000000000 lol btw.. thanks =] this video was very clear and i have my own dual 555 circuits working :D thanks to you ! nice vid!

[bellerve201]

hello there... you can also use potentiometers or varible resistors in place of the resistors or try using other resistor values.

[Flea5000000000]

@bellerve201 yep

[willymax0]

WoW thanx man, i really needed it, thanx a lot, i could made my homework thanx to u... i guess i´ve said many thanx but ... thanx LOL

[MrXMGS]

Thank you for the video it helped a lot.

[VPDxD]

in electronics we used two 47k resitors and 2 330 ohnm resitors and a 10 uf capacitor

[Flea5000000000]

@VPDxD ok

[tomek123kotek]

wtf parts bin? did you shake the internals of a semi old computer into there?

[Flea5000000000]

@tomek123kotek lol this is when i first started electronics I have one of them parts draws

[orbiter8]

Great video flea ;) 1 question please.. What is the name of the breadboard your using & where did you get it from please?

[Flea5000000000]

@orbiter8 I got my bread board in canada, NB, saint john in a place called mucmillens under the high way crossing.

[orbiter8]

@Flea5000000000 Ah ok thanks. I thought it sounded like you had a UK accent so I thought you may have picked it up here somewhere. I do have a couple of large breadboards already but I liked the layout of the one your using. Thanks for getting back to me anyway.

[Flea5000000000]

@orbiter8 lol ya iv got a British accent.

[Flea5000000000]

@orbiter8 and don't know to name

[MaverickGrabber71]

me and my son were doing this, and we tested it, but it didn't work, we checked over it over and over but it wont work. the led works but it wont turn on when we hook up the real +/- contacts, i dont know if the 555 timer is maybe burnt up, please tell me what might be wrong and how we can fix it! thanks!

[MaverickGrabber71]

@MaverickGrabber71 i meant  me and my son were doing this, and we tested it, but it didn't work, we checked over it over and over but it wont work. the led works but it wont turn on when we hook up the real +/- contacts, i dont know if the 555 timer is maybe burnt up, please tell me what might be wrong and how we can fix it! thanks!

[Flea5000000000]

@MaverickGrabber71

-Make sure the resistors are the correct way (10k resistor from positive to pin 7, 100k resistor from pin 7 to pin 8, a jumper/wire from pin 8 to pin 2).

-If that changes nothing make sure the +/- are connected.

-Check to see if the capcitor is not the wrong way around and that it is connected to the negative and to pin 2 or pin 8.

-Make sure the L.E.D. is not the wrong way around and that it is connected to pin 3.

-Make sure that pin4/5 are not connected.

[Flea5000000000]

@MaverickGrabber71

- Make sure the 555 timer is not the wrong way around.

[Flea5000000000]

@MaverickGrabber71 sorry in the first part I ment to say - (10k resistor from positive to pin 7, 100k resistor from pin 7 to pin 6, a jumper/wire from pin 6 to pin 2).

[omer8836]

your video is good but how about u connect SOME LED direct to battery on breadboard?

[YourBarelyLegal]

Great video. Would have been noce to have directions in the description. Overall, great job keep it up :)

[Flea5000000000]

@YourBarelyLegal I put directions in the video

[thewii552]

I don't want to be mean or annoying, but it is called a microfarad( not uf) and it is spelled capacitor

[Flea5000000000]

@thewii552 lol I know that was my first video + its shorter (the uf thing) so I say that

[demonbreed131]

its called a microfarad

[trickymanjon]

could i put a variable copasitator in it to have a variable fequancy say if i were making a strobe light

[Flea5000000000]

@trickymanjon you could but it is easyer with a varialble resistor

[Flea5000000000]

@trickymanjon you could but it is easyer with a varialble resistor

[iqubaldo]

Gracias, muchas gracias, eres un amor.

[PolishGuy89]

I made it but it does not work, I Used a 100OHM and 1K resistors,and a 10uF capacitor

[Flea5000000000]

@PolishGuy89 The first resistor connected to the positve line must be lower than the second one.

[sarelapini]

just to mention, you can use a potentiometer or LDR to change the frequency

[Flea5000000000]

@sarelapini yep

[starindamaking25]

Flea, how do you increase the output voltage without increasing the battery size?

[Flea5000000000]

@starindamaking25 well you can't increese it above the battery. or do you mean increase the output of the 555? If so you can hook up a transistor to the output

[michael10725]

I am very stupid when it comes to this... Am 46y/o so it may tak some time to learn i see... but thanks for taking the time to shoe me this... I Think it's gonna be better if I Where to buy this blinker already put togetherAnd I Put in my project... Thanks again!!! Peace!!

[dmanmoka]

Good tutorial tbh :)

[totetoBT]

you can also change time with R.

t(tau)=R*C

[Flea5000000000]

yep

[pdf861030]

use a resistor that will give you a 4volts of a drop across it.

[markalvinvicta]

hey, how can i convert a 9 volts battery to 5volts?? thanks

[markalvinvicta]

hey., how can i convert the 9volts battery to 5 volts?? thanks..

[Flea5000000000]

you can use a 5 volot regulator

[nawazsucks]

Hey where do we connect the battery

[Flea5000000000]

..........on the negative and positive terminal

[nawazsucks]

Where is the negative and positive side of circuit? I wiill be grateful if ant1 replies

[Flea5000000000]

the blue rail is negative and red is positive

[nonameddog]

stop shaking the camera -.-

[Flea5000000000]

sorry this is my first vid ): my other ones are better

[happyapple7]

I like these tutorial videos about 555. To do a led flasher certainly it's a classic to everyone on electronics field. :) keep going

[HowBoutDemBoyzz]

is a 2.2µF 50V 20% Nonpolarized Electrolytic Capacitor 9,000Hz okay? thanks!

[Flea5000000000]

2.2uf is ok, 50V is ok, I don't know what you meen by 20%, I don't get what you meen by 2.2uF and 9,000Hz because 2.2uf and one 100k and one 10k is not 9,000Hz unless you are changing the resistors.

[TheVBProductions]

where did you get that bread board setup? its nice.

[Flea5000000000]

a place called mucmilluns its a electronics store in saint john/new brunswick/canada

[supersanchez1991]

wow man is so strange the switch was off and the battery drain so bad. the switch is hook up, one wire to the positive lead of the led and the other wire to negative lead of the led. why that happen

[Flea5000000000]

? your saying that you put a switch on the positive to negative of the led?

[supersanchez1991]

yeah but the battery drain so bad

[Flea5000000000]

I don't get it where did you put the switch

[supersanchez1991]

lets just say that i put in in pin #1 and pin #8 of the 555 timer

[Flea5000000000]

why did you do that its just going to compltly drain the battery?!?!??

[supersanchez1991]

because i am a idiot. and yeah it drain the battery.i try to put the switch in the negative but it did not work

[Flea5000000000]

lol put the switch from the negative of the battery to the negative input on your breadboard.

[supersanchez1991]

a resistor on the negative of the LEDs? i thought resistors are be to use on the positive of the LED. thanks for the help.

[Flea5000000000]

it dosen't witch end the resistor gos on as long as there is a current running trough it (:

[supersanchez1991]

iam sorry for making comments that my be stupid for you, but i hope you can help me once again. i am making a word with LEDs, the word is LIZ it has 33 LEDs and i am using a 9v battery so i put a resistor of 12 ohms but after the LEDs been on for about 10 seconds, the resistor gets hot. you think i should put a higher resistor? and thank you once again for your help.

[Flea5000000000]

sorry, you should try a 330 ohms resistor and connect all the negative terminals on the LEDs to one resistor (if your not allreddy doing that), because it will just save you resistors, insted of using 33! :D lol

[xkikimex]

pure genius thx...ill make this

[supersanchez1991]

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

[Flea5000000000]

well... you would put it on the power source like- negative then switch then negative terminal on 555 - okay

[Calloween1]

its microfarad not uf hint hint nudge nudge

[Flea5000000000]

i don't care

[Flea5000000000]

O: sorry it dose look like it has a 3v power supply sorry its a 9v (: sorry

[Flea5000000000]

but if you want to put a 100k resistor on the input of the 555 timer and the 4017.

Because this scimatic has not been tested and edited because i don't have the parts i drew this up, but it should work.

[supersanchez1991]

one question how did you make a 9v battery to 3v battery? what are the resistors? how many did you use?

[Flea5000000000]

im not useing a err 3v bat . im useing 5v for the 7447 display chip and 7 seg display. no resistors were used i used a voltage regulator to make the power 5v. the 9v was for the 555 timer and the 4017.

[Flea5000000000]

he means scrach i think but iv allready posted it so whatever

[Flea5000000000]

thanks, your the first subcriber but i just got annother person subcribe

[supersanchez1991]

hey nice video. hey do you know how to wire a 7-Segment LED Digital Display? please respond. i like your videos.

[Flea5000000000]

yes i do, but i don't have a verry good suply of stuff. I will have lots more stuff in about a week. But ill post a vid for you showing the scmattic if you want.

[supersanchez1991]

thank you man, that will be great. thank you but if you can make a video showing how to do it when ever you get supplies that will be awsome. but i would like to see the schematic. thank you.

[davidbball13]

Supersanchez (totally sick username btw) If your looking for a logic 7 seg display IC. Look into the CD4026. Its a CMOS IC. I have a video of it in my channel. All you need is a clock (you could use the 555 from this video) into the chip and the a b c d e f g outputs to the 7seg. and you can use the divide 10 pin to add more displays

[Flea5000000000]

ok i have all the supplys but its a bit differnt ermmm i don't have the 4017 but it should get here in a week
