My goal was to create pro-haunted house level effects on the cheap. I wanted something that would be different every time you see it. Planning to combine visuals and sound, I created the monster behind the door effect. Through the window of the door, the viewer can see what might be happening behind the door. One time the viewer goes through might have a monster in the window trying to get through the door. The next time it would be a normal scene inside a house followed by the “monster pop-up” scare. Variety is my goal. It can turn a stale effect into one of constant apprehension.
The door’s window is, in fact, a LCD screen, making for an infinite number of possibilities. Also behind the door is an array of air-pistons to hit the door in various places to simulate commotion or direct hits. This door can be placed anywhere. Even at a distance, it has a frightening effect. This system could be adapted to work on any front door, as long as you don’t mind that door getting destroyed by pistons.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
