Hi there,
anyone can help me to solve the problem regarding the uploading program into arduino board? I'm using arduno duemilanove. At first I upload a program into the arduino board, and its work. Then I want to upload a new program, but it will appear "serial port already in use, try to quiting any program that may be using it". Therefore, what should I do to quit the program inorder to upload a new program?
tq
