How to use a motion sensor to trigger sound?
I'm trying to trigger audio with a PIR sensor but with no joy. I was hoping that someone on here would be able to help!
Oomlout SPD61 PIR sensor
Omron 5v relay g6a-234-bs
Voice recorder Cebek C9701
5v Voltage regulator L7805CV
with 9v battery attached and 8ohm speaker (these both work fine).
This is loosely based on the following instructable https://www.instructables.com/id/Sound-graffiti/
But the instructions relating to the wiring was not very detailed.
Some people have suggested that I would also need a transistor between the sensor and the 5v relay (which was not mentioned in the instructable), can anyone confirm this?
If anyone could draw me a diagram of how I'm supposed to connect the sensor to the relay to the voice recorder I would be so grateful!!
