Ok. Processing code is below, as is original pushbutton code for arduino. Am not getting anything in the serial monitor. I am using bytes because the code I had for a push button sends bytes, and this worked perfectly with the processing code so I thought I could just change the if statement? I haven't yet learned about ASCII. Can you explain why I need to use these instead?
Thanks,
Ben.
