Charlieplexing. The verb is an electronics technique apparently named after one Charlie Allen, an engineer at Maxim. It involves minimising the use of I/O pins on a microcontroller to drive a maximum ...

In this example, I am using three GPIO pins on an ESP32 to control six LEDs via Charlieplexing. The sketch demonstrates three different methods to control the GPIO pins, highlighting their performance ...

This open-source Enigma replica by the folks at [ST-Geotronics] is simply stunning. They drew their inspiration from a hilarious build we saw a few years ago that hacked a children’s toy into an ...
