How-to Tuesday: Fun with the Arduino Starter Kit

[dragoninfire123]

the pressure sensor looks like an electric piezel

[mrhowto361]

"Can anything else go wrong?"

#firstworldproblems

[joeybab3]

im going to get one of these

[wisteela]

Very neatly done.

[Cambesa]

How strong are those resistors?

[Importenator]

@Cambesa I think the color code is brown, black, red. So im assuming its a 1k resistor.

[Traxxas2012]

@Importenator i also think that it is brown black red.

[beveledkunt]

This is such good fun. Thank you.

[3dpelican]

Thanks, that helped me.

[olliecracker]

Thanks! :D great tutorial

[OSTycoon]

You were willing to bend your led's rather than cut them, but they you clipped your resistors.

[roofy2k]

i've never seen anyone bend the LEDs to take up 6x the space, then trim the resistors short...

[ranamuhammadatif]

Thanks a lot for this idea. You should develop a keyboard for your toes. Out toes need some exercise. That will be good for your health. It will also remind you to keep your feet clean so that they do not smell !

[patlecat]

Very nice tut, well done :)

[pietzeekoe]

jesus......how many lights do you have?

[nieknooijens]

@pietzeekoe you get 30 with the starter kit

[pietzeekoe]

@nieknooijens I was accualy talking about the lights in his recording area

[DEATHHUNTER1232I]

@pietzeekoe i counted 12 i may be rong i sooo tied

[DJMC5ive]

@DEATHHUNTER1232I I counted 12 light switches...but there was still light after that..

[nar98]

The code: blog . makezine . com / archive / 2008 / 11 / howto-tuesday . html

[defiancellc]

@itsaconspiracy1988 i think you're missing the point

regardless, i bet he could out-arduino you any day

[NorwayHack]

02:03

It's a bunch of penises!

[leonardo1480]

not meaning to sound dumb but what is a Arduino for I mean what is it's purpose?

[BoltAndPennyFan]

@leonardo1480 Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.

blablabla....

(Source: Arduino.cc)

[leonardo1480]

@BoltAndPennyFan hey man thanks for the Info.  all the best!!

[BoltAndPennyFan]

@leonardo1480 You're welcome buddy :)

[zagalofication]

when i connect 3 LEDs the second one gets weaker and the third gets weeker

[lotios611]

@zagalofication That's because you wired them in series. If you want them to be the same, wire them in parallel.

[IKameAndKilled]

hmm... cant seem to find the code. The link takes me to the wrong article. Does anyone know where else i can find it? I'll check the arduino site though, to see if it's there

[osmguitardude7298]

what type of resistors????

[photographe06]

I loved this - exactly the right level for me. Thanks!

[sbfunnypants]

the circut board part starts at 04:03

[bclaus0]

I like how you hold your pen the right way.

[wyllmRox]

couldn't you save resistors by connecting ground through a resistor instead of all the positives? and doesn't pin 13 already have a resistor?

[Slench101]

howcome the new starter kits don't include a protoshield?

[wyllmRox]

@Slench101 they do..... you just have to put it together. it's in a zip plastic bag with the protoshield pcb, two LEDs, two pushbuttons, and some connectors. You can look up how to solder it together on ladyada.

[Slench101]

@wyllmRox it's not on the list of included components on the store page...

[wyllmRox]

@Slench101 it is in the adafruit kit.

[Slench101]

@wyllmRox but not the getting-started-with kit

[MultiJohn12321]

@killul yes

[VigilianceAurelious]

Well about the LEDs

Just in case I cut the LED's wire and makes the wire look the same length

one way to determine the negative one is to look at the bulb thing-y of the LED and look for the FLAT one. That's the negative wire of it.

[SoundsFantastic]

If those are 1K Ohm resistors, isnt that kinda high? Depending on the exact diode forward voltage and current you could use much smaller resistors.

[plecharts]

There is no need to add resistor to pin 13 if you are only lighting up an LED, there is already integrated resistor.

[MrJackpoppy]

anything else go wrong how about your com ports stop working dont buy a uno smd utter shit boards

[khaledmalsalman]

helli

I just would like to ask if it has a USP version like the boe bot

I am using a mackbook and it would be difficult to find a computer with a serial port

plus i was confused with the huge amount of numbers of boards.

I have been working in different microcontroller and I program on C and C ++ and I could not find on the internet the right board to get.

I am looking for a board which allow me to make a small robot with 2 motors a few leds .. sound output or input device ..

Thanks

[SoundsFantastic]

The current protoboard for the new uno doenst have a breadboard, does that come in the kit?

[Rob0tSecks]

@SoundsFantastic  it's just a mini breadboard you stick on with the self adhesive.

[timothee64]

Hello where i could buy a the proto board??? Thx a lot

[Rob0tSecks]

@timothee64 eBay sells them along with tons of other Arduino stuff.

[aseskns]

i'm always scared to try and make some circuits at home,but i guess that usb bredboard thingy seems safe enough.

Looking forward on buying this kit looks really fun.

[BloodHassassin]

awesome sketch there!!

[hitmanhite]

cool

[hymcwtmc]

May i ask what are the resistor values? The ones that connect with the LED's and the sensor?

[hymcwtmc]

You sketch really good. Nice vid btw!

[francisroan]

u asked if anythin else can go wrong .....so did anythin else go wrong????????

[MisterModder123]

The LED's at 3:58 look like penises :P

Very cool video though!

[bears7777777]

You should teach us how to make a scale to measure things, thumbs up if you would like this

[oblanob]

i love the way americans say"sodering" instead of soldering...

[jjmd845gunLOVER]

type prize before youtube then press enter

[EtheB1]

An interesting little project clearly explained and really well put together - thanks!

[techguy19]

u sir..... are an artist XD

[NaiveAmoeba]

awesome, have to check this out! great vid.

[wbootle]

3:06 looks like a menorah!!!

[makmegs]

lets do some charlieplexing next

[ktskid]

Does this starter kit still come with all of the things that are used in this video?

[wbootle]

SIMPLE Illustration huh?

[RichyBTheking]

Really cool vid mate well described and easy to follow... also dude how many lights do you have in your room lol

[Rui1973Martins]

You better start to trim your LEDs, because you are heading for disaster.

Those long leads, of consecutive LEDs, put negative(GND) and positive(VCC) right next to each other. if for some reason, you push the LEDs arround, they will touch each other, ie. a short circuit between gnd and VCC (through a resistor) and will probably burn your arduino or some part of the board.

[doscientist]

ahm never worked with arduino so, wouldnt it be the same if u plug all leds in one pin ?

[silverpizza100]

So 100 bucks for that. OMG Kill me now. What is this crap? You think your Bill Gates or something? This is junk. Dont waste your money on cheap goods from china, Buy a gun and store up canned foods.

[97Longrange]

@silverpizza100 ma by people like to do other things than drink beer and watch football

[thepicklesandi]

@silverpizza100 Actually, the Arduino Uno is under $50, and it's made in Italy. =\

[MasterChafed]

@silverpizza100 lol, if you are so against the Arduino, why are you trolling all the videos?

[webvid91]

@silverpizza100 i dont need to buy a gun and store up canned goods if the worlds gonna end in 2012

[hyper080]

@silverpizza100 i paid 50 for it and now it is the autopilot for my rc jet

[bears7777777]

@hyper080 if you are serious you are awesome.

[hyper080]

@bears7777777 look at diydrones . com / profiles / blogs / ardupilot-main-page

[mtemal]

You have a great eye for graphic design and board layout. very very professional. Thanks for the video.

[beasterG11]

does the ohm rating matter on the resistors

[dlmarti]

@beasterG11 yes. The resisters are chosen to limit the current through the LED to 20ma.

[themanwithaplan13]

Thumbs up if you think the LEDs he drew looked like dicks!!

[floryzzz]

He killed 11 of the lights en there still enough for light to film

[thebmr321]

watch this video with the translate captions on it hilarious

[TheCODpro20098]

Kids be warned spam below thumbs up if spam is driving you insane

[yoyohoes]

wow u must spend so much time looking at the shield

[MYEYESONECONOMY]

let's kil the lights xD "click""click""click""click""c­lick""click" pause "click""click""click""click""c­lick""click" xD

[MrStation37]

I thought the same thing. He must be in mexico or somewhere that has those really hard industrial type switches.

[Bvzijverden]

Where can I get a kit cause I´m kidda a starter so I wanna learn more about this :)

[halotechy]

@Bvzijverden

here liquidware com/shop

[TheWissenschaftler]

@YouPeda THX

[TheWissenschaftler]

can i have the code please or a link ????

[YouPeda]

@TheWissenschaftler Look in the Information Box. There is a link to the code ;).

[TheWissenschaftler]

@YouPeda THX

[neighbor98]

dosn't pin 13 have a built in resistor?

[tkfreak1]

@neighbor98 yep you´re correct so actually this led should be dimmer than the others but maybe the camera just doesn´t get it right

[roofy2k]

@neighbor98 pin 13 has a 1K resistor in series with the LED on the board that makes it pretty much bypassed when using it as an output

[samtheman1993388]

2 questions?

1: Where am I able to find a copy of the sketch?

2: Where can I buy the pressure sensor from without buying the entire starter kit?

P.s great video :)

[dlmarti]

The first time I hear someone I hire, call a program a "sketch" he's getting smacked.

[leylachristina]

We really liked this project. Could you suggest a way to modify it so it uses an Infra red beam instead of a pressure sensor, so that the LEDs turn off when the beam is interupted?

[dillonis4real]

i was really hoping you could send me code to use this same circuit with a potentiator knob instead

[ciolamorta]

I want O'Reilly pen

[larinko]

Hi i want to make an led light bar for my rc car and i was just woundering if u would use one of them and do u have to have a pressure switch thanks

[dodgedart74]

doesnt electrons flow from the negitive to the positive? so why re you resisting th eline, after it has already passed through the led?

[NGYT40]

Can you apload a demonstration with the code?

[NGYT40]

Can you apload a demonstration with the code?

[krisis117]

I have question-in the starters kit Arduino need to be build up or its ready for use???

[howardrya2]

what sise resistor do i need?

[thejavor5]

how do u make your jumpers

[Merker7Inteligents]

I'm Sorry to say. but this is kind of pointless. Is's good for people starting out by making this thats new to electricity but it is just a little waste of time.........

[golthak]

Great video. I liked how you started by drawing what you were going to make and talking through all steps. I was just about to ask if the rails on the breadboard were connected, but then you mentioned it. :)

Thumbs up.

[BlanchProductions]

Not ot be a creeper but...766 39th ave Sanfransico Ca

[b0bb0bs0n]

so does the pressure sensor basically act as a variable resistor?

[BarrykeNL]

@b0bb0bs0n yes

[Fockoel]

where can i find the code?

[lhomes99]

the redundant/boring stuff is great for those just starting out to understand what is really going on -- great video

[conor1148]

i agree, if it wasnt for the "in between" stuff, you dont start to make the connections between how all these examples work together.

[thebra]

Great video but you should edit your videos to cut out the redundant / boring stuff.

[hershelt]

nice o'reilly pen

[ubaid1987]

This is great

[wawcoldfire]

actually you left the ground pin connected to the resistor on the far right unconnected by the red short connectors

[mkillerz979]

There is a 15% off coupon just search it up

[LuciusMare]

Haha @ the beginning :)

[macOSXhelp1]

60 dollars USD

[Pvsmuntje]

Where can I buy an Arduino Starter Kit for 60 dollars USD?

[19ingen]

@Pvsmuntje you can buy this kit from sparkfun

[94thts]

"Lemme kill some of the lights here" *click**click**click**click**c­lick**click**click**click**cli­ck**click**click**click**click­**click* ... LOL how many lights you got in one room?

[jodex96]

Well good lighting is very important on making a video. But ain't just couple of lights enough?

[sebastianblevdet]

@94thts and it was SOME if the lights^^

[alyl603]

@94thts he still had about another 15,128 left on...

[AndrewWCo]

@94thts That is the best part of this vid...LMFAO!

[TANKADUB]

@94thts exactly wat i thought haha!

[DrDiablo36]

@94thts hahahahahahahaha best line ever xD

[kinsi55]

@94thts

he turned off 10 of them :D

[awesomelegoguns]

how much does it cost plz tell me somebodyy

[TomHaste]

I just got one for $60AU. Thats the whole starter kit.

[Nuchuga]

$60.00 usd

[kmiondeuvas]

Hola , si son de latinoamerica busquen arduino en olimex chile.

Hello, if you want some arduinos, try searching olimex chile

[buggyiscool]

anyone know if you can make a code delay by an int variable like this "int time = 1000; delay(time)"

or is there a correct way to do that

[jeanbrouwers]

you can: use it

int time = 1000;

delay(time);

[buggyiscool]

why cant schematics be like your drawing!

[brad346326]

how many led can you hook up to one pin thanks

[koekoeka]

Should I buy an Arduino Starter Kit or the Boe-Bot Kit?

[Didanix]

Which pressure/force sensor is he using in this one? I still haven't found a reasonably priced pressure sensor, so just wondering.

[omlan]

Lol i can't find them anywhere, except Sparkfun, but the thing im looking for is a bit like this but not exactly, AND FROM SPARKFUN ITS LIKE 30$

[XxeghoffxX]

im thinking about buying an Arduino but, i just want to know one thing: if i build something, will i be able to take all the parts back and build something else or do i have to buy some new components?

[Crinjagizmo]

well just unsolder the parts xD

[jodex96]

You can just take 'em off. Recommended to buy it =)

[isaaccade]

Yes, don't solder, use tape. (eletrical tape)

[hoolaput]

i wish i had your protoshield

mines retarded i bought it from fungizmos the v.4 one and the mini breadboard hangs off the edge of it. it lookd retarded and the leds don't even work.

[vikthefreak]

sorry for the stupid question, but why were the resistor necessary? I'm not an expert, nor I studied engineering. Thanks in advance for the answer.

[fireraisr]

so you don't burn out your led's, they limit power

[jwjustlookin]

Resistors are needed to reduce the amount of power that is flowing through the entire circuit, also for the LED's

[madnessdexter]

LED when on acts like a closed switch so with out the resistor there to limit power the LED would burn out.

[Froggy19510]

I've watched this video at least ten times, and every time I watch he breaks his pencil. Why doesn't he get a better pencil?! LOL

[doughty74]

Do you have enough lights in that room.

[teddybelle]

This video helped me alot. I wish there were more videos with drawing out the plans, breadboards, soldering, and arduinos. I'd also like to know how strong the resistor is. (I'm not asking too much there, am I? ;-) )

[collinw24]

330 ohms

[fjmerric]

lot of lights

[theglurgle]

1. It's a pencil

2. O'Reilly is the company that owns Make Magazine.

[DragonChamber]

what does "sub" mean?

[Pantholder0]

are there any good books that can teach me to write that code stuff. i want to learn it

[chieffw]

Well it is basically C/C++, there are tons of books on that, it uses the same algorithms, but there are a few extra commands which you can find on the arduino web site

[DragonChamber]

it uses C, and most languages are based off of C anyways. An algorithm is how you solve the problem, so it could be the same, but it may differ, because everyone is different. Yes, they have tons of methods that help out! :D

[modman1234567]

1:25 THATS WHAT SHE SAID LOL

[Givemeapix]

HE.

NOT SHE, HE!

Over voltage? You can exceed the watt limit of the resistor... but follow me... voltage output of the Arduino is probably 5 volts (Standard for TTL and CMOS logic). Most leds use about 20mA.... so a maximum of 0.1A. Power calculation is P=VI or P=(I^2)*R. Since we know the voltage and the current we will use P=VI.
