hi, are you able to guide us with something more advance, like connecting multiple fingerprint reader to operate multiple locks which are independent of each other, but installed on a single board.
i have a issue with my fingerprint sensor. When i connect the red and black wires, my sensor doesnt light on. It is flashing blue light then it turns off. On serial monitor, the error i have is fingerprint sensor is not connected :( any potential fix pls?
