May 05, 2021· Hi, I’m fairly new here. I made a project with a 4-relay shield, operating 3 DC motors and I got that working. I even worked out how to run the program only once. I did this because I want to make it run once (or max 4 times) when a Passive Infra Red sensor with timer has been triggered. When someone passes by, butterflies will flutter about… How can I connect the 3 pins of the PIR/Timer ...

Feb 03, 2019· A little bit of back story. This project was actually built before my Motion Activated Door Display aka. Arduino Project #8. Because, I was still waiting for the WS2812B boards that time and remembered and asked my self "Hey! I have a couple of PIR motion sensors in my Arduino …
Then we declare the relay pin as an output (signal only go from Arduino) and we declare the PIR sensor pin as input (signal only goes into Arduino). Finally, we use digitalread to get a reading from the PIR sensor which is either 0 (no motion) or 1 (motion) and store it into the variable val.
