8 LED Chase Controller (Project)

Description:
A bare-bones controller used to drive 8 single color LEDs. Based on an 12F675 and a high-power shift register, and single push button for control. Altering the source code allows custom patterns to be added. Good for Case Lights, Infinity Mirrors, ambient lights.

 Features: -
8 Channels - 4-state PWM - Up to 200ma per Channel - Very Low Part Count - 5 Patterns - Free Source Code for adding custom patterns - Easy to add ICSP. Specification: Input Voltage Input Current Output Connectors Dimension 3.3 - 6v* 700 ma** 8 Current Sink Channels 0.1” Pitch 1.5” x 2” x 0.5” *Kits are setup for 5 volts. **Based on 32 LEDs at 20ma each.
