Twitter user @caitlinsdad made this insanely awesome maker-themed ice cream truck. Inspired by his idea, here is a guide on how to create the truck in its physical form! Using cardboard, a couple different motors, NeoPixels, CRICKIT and Circuit Playground Express, we will recreate this totally tricked out truck!
