Special thanks to long-time Parallax friend and contributor Carol Hazlett for this spooky Halloween project idea!
This is an easy-to-make window display for Halloween using the Propeller Activity Board WX, a speaker which will play wav files (I used a Portable Hamburger Mini Speaker), some RGB LEDs, and a 3D printed or store bought hollow Pumpkin.
Some soldering is required for the (#28085) RGB LEDs used in this project. Instructions assume the LED modules are fully assembled and ready to use.
This is my finished pumpkin display. When I put it in a window, I like to use a small black piece of cloth around the platform to hide the "on" lights from the ABWX and speaker.
I pre-tested all systems before the full assembly of the pumpkin to ensure everything was working as it should. This can be done after assembly as well, but it is simpler and easier to make wiring changes (if necessary) before it is all put together.
And here is the Blocklyprop code I wrote to run everything. Please feel free to improve it!
I hope you enjoy this project.
