This project's goal is to create a controller for an HDD clock built based on the persistence of vision principle. The previous controller solution used an Arduino and breadboard to control the LED's inside the clock, and manage the infared emitter and sensor used to determine the location of the disc. Though it worked well, it was unwieldy. Therfore, this solution aims to provide the same functionality as the original, save for in a smaller and simpler package, namely:
