Is the Elgoo Uno R3 different than the Arduino Uno that is referenced?
The Uno uses an ATmega32U4 with a custom firmware created by Arduino.
Back in the day, we used to have Adobe forums that met once a month so developers should share ideas. Do these in the form of Arduino ever happen? Coders helping coder noob?
it should say either 'MEGA32U4"
it should say either 'MEGA16U2"
