Note that this system only caters for one switch being operated at any time. If you google R-2R you'll get info on how this is accomplished
Hello, I want to connect several switches to the same pin interrupt. Each switch has this schematic:http://www.arcan.es/wp-content/uploads/2009/03/reset.jpg[/img]]But my switches are NC, normally closed, then, the arduino can not detect the interrupt of several switches. It can only detect if there is one switch connected.Can anyone tell me how to solve this? How can i connected several switches NC to the same pin?Thanks,Regards.
