I am building a Halloween prop and I'd like to add sound to it.
I was looking at this cheap solution:
It's a simple playback device. It has an input for a switch. I want to tie that input to a relay so when the motion detector is tripped it triggers the sound.
When the detector trips, it will supply AC to a power strip. One of the things plugged into the power strip will be an 8VDC supply to drive a DC motor. An incandescent light will also come on.
In other words, when the detector trips, I will have 120 VAC and 8VDC available to me.
Should I go with a AC or DC relay? Any specific info as to which one? I'm going to be ordering some stuff at allelectronics.com.
