For Halloween I thought it would be great to take one of those pumpkins you always find at the hobby store, like Michaels, and put some LEDs in it. I wanted to do more than just have them all on. I wanted them to blink in interesting patterns. I realized I could use the board I created for the FiveSquare project, which uses a PIC16F648. With this I would be able to control and animate 25 LEDs. I also realized I could add a new layout to the Animator application that matched the arrangement of LEDs on the pumpkin and be able to easily create different animations.
