I am trying to make an the uno read from two RFID readers at the same time. Whilst it is possible with using the code I have, I have managed to make it read one at a time, due to the power (I think) When I put a pin from 5V to one it works, and then to the next it works - but when I try to run them from the same pin, it doesn’t!?
I’m fairly new to arduino, so any help would be great!
I’ve attached the setup I’ve created to make it work! Like I said, the arduino is reading from both fine, but it seems the power is not powering both up at the same time.
Hope you can help
