Last issue, we brought you a clock with digits that slid up and down to display the time; this issue, we’ve discovered a leap forward from this, with grids of black and white squares sliding up and down over a red light source to make digits. It’s powered by an Arduino Mega that controls eight small stepper motors, and there’s a real-time clock module (DS3231) to keep track of time.
