I'm having issues controlling a single relay module with an arduino. It works fine when its up and running but the relay initially starts triggered until the arduino can send a "high" signal to turn it off again. I should have used a high trigger relay instead of a low trigger one.
My question is whether I can use a pull-up resistor on the input of the relay (being the output pin of the arduino)
both the arduino and relay are powered by a common 5v supply.
