For some reason I can't get the arduino to print a simple "Hello World". It first started with me trying to read a value of the potentiometer and all it does is print random characters like ?%do&?de?. Can someone maybe tell me how I should fix this? Thanks!
Baud rate on serial monitor matches program?
I have Serial.begin(9600); That’s what it should be I believe. It was working fine earlier today but now I don’t know what it’s doing.
Try 19200 or check the drop down on the serial monitor to verify it is at 9600.
I eventually got it working at 9600 thanks a lot!
