Hi, Scott here from Salem. My program goal. Press 1 on the key board and an led lights up on the arduino. Press 2 and it goes off. Press anything else and the command port prints out 'invalid'. Codevisionavr Serial Experiments.

I then want to clear the serial port to erase anything else, because if I press a bunch of numbers e. Konkani Baila Songs Mp3. g. 3456, it prints out invalid several times. I would like it to print out invalid only once. I read that Serial.flush() no longer works. I have tried byte = discard Serial.read() but this does not work. Can someone help me with how to flush the serial port of the remaining data? Here is the code.
