programming - "stray '/302' in program error" when
Oct 26, 2016 · One cause of the /(302) error is copy and paste code from a word processor. You have ASCII codes copied that add spaces, etc to your code. Go through each identified line and remove any extra spaces at the beginning and end of any identified line. Then, (Arduino IDE) go to TOOLS, Auto Format. At least, this cleared up the problem for me.
