Research

  • Buy book: Art of Electronics
  • Pulse width modulation in RGB LED can be hardware or Software

  • Charileplexing N- number of pins number of LEDs that can be controlled is Nx(N-1)

Design

I wanted to try working with and controlling at least 2 RGB LEDs in my board. I also wanted to give the board networking functionality for future assignments.

Fabrication of board

Programming

Problems & solutions

Goals Achieved:

  • Describe the design & fabrication process
  • Describe / explain programming process
  • Outlined problems and how I fixed them
  • Include originals design files and code

Original files:

Blinky board Traces file

Blinky board Cutout file

Blinky board Eagle board file

Blinky board Eagle schematic file
