12. Output devices

This week I worked on defining my final project idea and started to getting used to the documentation process.


  • 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)


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.
