hi Erik Sjödin, WARNING: You can destroy your Raspberry Pi playing around with the GPIOs if you do the wrong thing!!! Did you look at my circuit? It has resistors!! Very important. A lot of people advise using a transistor buffer for extra safety. For input circuits you are supplying the 0 or 1 (0 volt or 3.3 volt) Note: The Raspberry Pi GPIO naming conventions are confusing. Make sure you are connecting to the right GPIO. regards Greg ------------------------------------------------------------------------ Greg Erskine's Profile: http://forums.slimdevices.com/member.php?userid=7403 View this thread: http://forums.slimdevices.com/showthread.php?t=97803
