Introduction: 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:
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
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 forback.io to cool led lol

I hate to sound real dumb.....but what does it do?? I am looking for something that would turn on random leds for a random length of time. Perhaps 12 to 20 leds in the group. I want to randomly light windows in the buildings on my Ho train layout. Like people entering and leaving rooms.

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

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