I'm working on a box that opens, plays sounds, then closes. I would like to trigger the opening with a motion sensor that opens the lid and the sounds start to play (little over a minute). I've ordered a 200 second recordable module for the sound and to open the lid I'm thinking about a cordless screwdriver (batteries removed and rewired for transformer), connected to all-thread for a make shift linear actuator to open the lid, hitting a micro switch to turn the screwdriver off. Will use an ice cube relay (120v 4pdt 3amp 28vdc) to start the ball rolling for the multiple items. I'm struggling with how to wait for the sound sequence to finish and send reverse polarity power to the screwdriver to close the lid. Motion sensor would restart sequence. Any help would be greatly appreciated. Thanks
