Introduction: How To: Really Cool Led Script for Arduino

Picture of How To: Really Cool Led Script for Arduino

a kindof simple sketch I made fro leds with Arduino for s sick effect of the leds!

Step 1: Hardware Needed:

Picture of Hardware Needed:

1) Arduino uno R3

2) 12 light emitting diodes [leds and you can use more than 12 or less than 12 if you want]

you should have an even distribution of the leds: in this case 3 red, 3 blue, 3 green, and 3 yellow leds.

3) [4] 220 ohm resisters {band sequence- red,red,black}

4) 9 bread board jumper wires

5) Solderless bread board

6) the sketh that I will provide for you

Step 2: Put Leds and Resistors Accordingly

Picture of Put Leds and Resistors Accordingly

follow the picture

You should use different color LED's to make it look cool

Step 3: The Code [sketch]

here is a download link for the code above.

I forgot to change the name from to cool led lol

Lovely code, but if I may say so constructively; that photo is really awkward to copy from. You'd have such an amazing page if you provided a bit more info and clearer images or diagrams to anyone less experienced. I think there's free software out there for making handy diagrams of stuff like this.

I'm also in the process of updating these photos with diagrams

looks like an interesting little project however, your instructions are not that clear - especially the circuit ,,,,,

alexb369 (author)rorywquin2017-03-26

sorry about that I will make better and clearer instructions in the future

alexb369 (author)alexb3692017-03-27

also I updated the picture of the circuit with a diagram

Great Intro to Arduino project. You should definitely enter it into the Make It Glow contest.

Thank You!
