Designing A Compact RGB 14-Segment Display

Sometimes you’re looking for a component for a project that you know should exist, but you just cannot find it. Something like a 14-segment LED display, but not just one with a fixed color, ...

Engineers builds Arduino-led game console from a fidget clicker and I want to fidget with it so badly

Arduino test code is run to see if the sensors are working properly, with built-in LED flashing when the sensor is triggered, and turning off when the sensor is released. The testing of the keys ...
