Relays constantly on using a multiplexer.
hi i working on project consisting of 8 relays. is possible use multiplexer control relays by cycling thru channels , providing power needed relay thru multiplexer's common. as far know wouldnt problem turn only 1 relay on, if use multiplexer only 1 channel can output voltage @ time. i pretty sure relays respond slower than the arduino's clock. so wonder if looping thru 8 channels fast could keep relays on constantly? if would, should damage relays? is there better yet simple way this? thanks. the simple way serial-in/parallel-out shift register. gives 8 separate outputs can individually controlled. see: http://arduino.cc/en/tutorial/shiftout Arduino Forum > Using Arduino > General Electronics > Relays constantly on using a multiplexer. arduino
