Arduino animatronics- make your awesome costumes more awesome!

Step 5 Now let's have some fun!

Example 1- LEDs
 
This is really simple- we're going to make two LEDs blink and another LED fade. The code will run over and over as soon as you apply power.

It's really easy to set up circuits like this using a breadboard. With each example I'll show how to wire everything up using either the servo board or an Arduino.

Copy and paste this sketch into your Arduino window-
