multiple 28140 rfid readers problem with reading
I'm working on a program that uses multiple rfid readers at different locations to read rfid tags. I'm running into the problem that i can't get the two readers to work on one arduino mega or on two separate arduino unos. On the mega they work separately but as soon as i put in the 'enable' of the other reader it stops the reading for both of them. Here's my code for the mega, I would really appreciate your help
