Simon Modifications

Favorited Favorite 0

Learn how to take your Simon Says board, add sensors, and reprogram the microcontroller. Learn about adding analog sensors to your Simon by creating a voltage divider and attaching it to the analog sensor pins. Then learn how to use an FTDI to load new code onto your Simon and change how the buzzer, LEDs, buttons and additional analog sensors function.

Concepts that will be covered include:

  • How do you make a voltage divider based sensor?
  • How do you solder a voltage divider based sensor to your Simon?
  • How do you reprogram the Simon?
  • How do you program inputs and outputs on the Simon?
