As the spookiest day of the year approaches, we here at littleBits have been cooking up some supernatural projects to trick out your Halloween. The interactions in both of the following projects are surprisingly haunting and would be a great addition to any haunted house or, if you are the Adam’s Family, a permanent wall fixture.
Great Uncle Edward
This portrait may just look like a normal photograph, but take a step closer and you will notice something very strange. The eyes in this portrait physically move, and not only that, they follow you wherever you go! We used an old frame, a photograph, motion triggers, a servo, and a series of logic Bits to achieve this unnerving interaction. This is one of our most complex circuits yet! Learn more here.
‘Come with us’, two small ghostly figures beckon. As you draw closer you hear a rattling sound. The figures suddenly quadruple in size and appear very close to you. Run away!!! The Ghost Projector uses a motion trigger and an inverter to switch between two ghostly images printed out on transparency paper and projected on the wall with bright leds. The images are angled in such a way that they appear in the same frame and alternate depending on whether or not you are detected by the motion trigger. More information about this spooky light trick here.
Stay tuned for more Halloween project ideas next week!
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
