Thanks for your time! I know that you are a busy dude. So this fix worked for the UNO.

I ahve a Pro Micro I would like to incorporate into a project. When I try to compile the same code I get this error:

Arduino: 1.8.13 (Windows 10), Board: "Arduino Micro"
 
F:\1robomaker\Robot Lab\resource\Arduino\MrlComm\MrlComm.ino: In function 'void setup()':
 
MrlComm:89:22: error: no matching function for call to 'MrlComm::begin(Serial_&)'
 
  mrlComm.begin(Serial);
 
                      ^

     void begin(HardwareSerial& serial);
 
          ^~~~~

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Any thoughts on the Arduino micro issue as previously posted?
