Apr 9, 2015 at 11:52 comment added Pita There is a button (and a 220 ohm resistor) between the 3.3V pin and the GPIO25. Yes, they run the same script. It now works if I connect both ground pins together; but I wonder if this system is possible without having to connect all the ground pins..

Apr 8, 2015 at 15:40 comment added joan Presumably your wiring is faulty. How is the switch connected to gpio 25? Is the same software running on both Pis?
