I received the 5V power supply to run the wiper motor for the Kiwi controller board for the seance room and it works perfectly. All the components are happy and working together now.
The Kiwi board controls the entire scene. When the PIR is triggered, it starts a wiper motor on the rocking chair, starts the moving books, turns on the LED lights on both the books and the rocking chair, triggers the Tenda board to start and runs the jaw servo on the skeleton. After the skeleton says his piece, the audio, the rocking chair and its light stop. A second servo pushes down on the DVD remote and starts the Madame Leota projection. After it finishes, the moving books and its lights go off and the system waits for 60 seconds before it can be retriggered.
Everything including the PIR, Tenda board, Kiwi board, components, speakers and power supplies came to around $80 with the 5A power supplies costing $30 alone. I have to order some off Ebay to cut down that cost.
I'm posting it here instead of in its own thread as the few people interested seem to be following this thread.
