Hi there. Many thanks to your great efforts. I'm trying to build RC car with mecanum wheels. I wanted to use my old Syma remote controller on this project. I have very little programming skills so I couldn't figure it out how to fix below errors in Arduino IDE.

Arduino: 1.8.13 (Mac OS X), Board: "Arduino Uno"
