Arduino COM3, COM4 HELP Answered
Hey, I recently bought an Adafruit Motor Shield 1.1, but i'm having problems programming it. Everytime I try to upload a program, it tells me it cant find the COM4 port, only the COM3, which doesnt finish uploading. Also, COM4 works fine when I detach the motor shield from the Arduino UNO and play with LED's. I'm only a beginner, so I have no idea what to do.
