This prop controller board is designed to trigger Halloween props that have the try-me button.
An on-board regulator provides power (nominally 4.5V, but adjustable) for the prop. No more batteries!
It has a PIR (or step pad, etc) trigger input and a trigger output to the prop’s try-me function.
It also has a switched aux 12V output to drive some scene illumination. The time that that aux output stays on for is adjustable as is the lock-out time.
This means you can adjust it to suit your prop’s run time and not have it trigger continuously when people hang around too long.
Only 4 connections to the original PCB.
Just 2 to the battery contacts & 2 to the try-me wires.
Most times the connections can be made without having
to remove or solder to the prop PCB itself.
The prop plugs into the 4 pin connector.
A 12V aux output connects to the scene illumination.
The trigger input can be used with a PIR, step pad, etc.
