I'm trying to understand serial communications on Arduino boards and would like to understand the difference between an Uno and Leonard/Pro Micro boards
I am working on a project where I send serial data (through the USB port) from an Arduino to a C# program on my computer. I have successfully done this using an Uno board as a test case using the Serial.println command.
For the final version I would like to use a Pro Micro board as I would like a small form factor and also needed more interrupt pins than a Uno/Nano.
So far I have successfully managed to send data from the PC to the pro micro but data going from Arduino to PC does not seem to work. I can confirm that the Arduino is sending the data as I can see it in Arduino serial monitor.
Is there a difference in the default serial output between the UNO and Leonardo boards? If so, is there anything I can change to make the output the same as on an Uno?
Thank you for your help
