Hi, I am behind B4 I start. 1) New, to the forum, 2) First experience with Arduino boards, 3) Old, retired, & mentally challenged with electronics,
My question is: How can I get piezo operate a small relay? on the UNO board I would like the piezo to operate relay to make & break a closed 3vdc circuit.
I have looked it the Arduino Knock, but cant find anything operating a relay. I would really appreciate if someone could give some direction. (to be honest, show me how to do it) No Idea Thanks in advance
