Liquid Lifebar Arduino Project Build
YouTube user Bfayer posted a video of his first Arduino project--an illuminated liquid "lifebar" that depletes and replenishes based on the stats of his Terraria game character. He paired an Arduino Uno board with a USB motor controller and linear actuator to pump water from a box wine bladder through a tube, which is then illuminated using an RGB LED system that correlates with the health or mana bar colors on the game screen. The video documents 100 hours of the project build in time-lapse, and lists all the components used for making it. The only apparent hitch: the motors are really loud.
