Fastest finger first indicators (FFFIs) bring precision to quiz games, measuring contestants’ reaction times with accuracy.

The below circuit diagram uses Arduino UNO R4 WiFi as a main controller, but you can use any other microcontroller by swapping it and making little modifications to the code. Here I decided to use ...

Metal-halide perovskites show great potential for efficient light emission, long-range carrier transport, and scalable manufacturing, making them potentially ideal candidates for bright LED displays.

This repository documents the creation of a 3x3x12 LED matrix that enables users to play a fully functional 3D Tetris game. The project leverages an ESP32-based development board (ESPduino) with ...

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Abstract: This letter introduces an analog pulse width modulation (A-PWM) pixel circuit for progressive-emission (PE) active-matrix micro light-emitting diode (AMμLED) displays, which is enabled by a ...
