From your very first blinking LED to dazzling multi-color sequences, Arduino makes it easy to bring light to life. With just a board, a few LEDs, and some code, you can experiment with patterns, ...

If you miss the days when you used Basic on your classic computer or wrote embedded software with a Basic Stamp, then maybe dust off your Arduino UNO or any similar AVR board and try nanoBASIC_UNO ...

Daniel Ansorregui has developed LightInk, an open-source solar-powered E-ink watch inspired by 90s solar digital watches. It ...

If you were to point to a single device responsible for much of Hackaday’s early success, it might be the Arduino Uno. The ...

Previously restricted to the four walls of a facialist’s clinic, LED face masks have now fully broken into the mainstream, with an increasing array of skin-tech brands offering at-home light therapy ...

LED face masks have come a long way since their early days as clinic-only treatments. Nowadays, these futuristic devices are as commonplace in our everyday routines as they are in high-end spas, and ...

Measuring the speed of a rotating object is a common requirement. Knowing the speed of table and ceiling fans, as well as kitchen appliances such as mixers and grinders, can often be useful. However, ...

This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...

Velxio is an open-source, self-hosted simulator for Arduino, ESP32, and Raspberry Pi boards that works directly in your web browser. You can drag-and-drop boards, connect components and modules, write ...

This is a port of Arduino to the RP2040 (Raspberry Pi Pico processor) and RP2350 (Raspberry Pi Pico 2 processor). It uses the bare Raspberry Pi Pico SDK and a custom GCC 14.3/Newlib 4.5 toolchain and ...
