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

After some time the controller turns the servo again in the opposite direction to close the dustbin, then the whole process is reapted again. The image below shows the Arduino circuit diagram for ...

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 ...

Abstract: This paper presents the design and implementation of a novel matrix-friendly genetic algorithm (MGA) based population input memristor circuit. Selection, crossover and mutation operations ...

The Mijia Smart Dumbbells feature an intelligent LED dot-matrix display that provides real-time updates on exercise metrics, including repetitions, duration, and calories burned, directly on the ...

Nollywood has unveiled a revolutionary movie, Ruthless, which premiered on December 20, 2024, exclusively on Circuits ... West Africa’s inaugural female-led mixed martial arts (MMA) movie.

Few things excite a Hackaday staff member more than a glowing LED, so it should be no surprise that combining them together into a matrix really gets us going. Make that matrix tiny, addressable ...
