This tutorial will guide you through creating a DIY Piano RGB LED Visualizer using Arduino and WS2812. No professional tools are required, making it a great project for beginners. Connect the data pin ...

This project creates a real-time audio spectrum visualizer using a microcontroller (Arduino/ESP32), a microphone, and an LED matrix. It analyzes audio input, performs a Fast Fourier Transform (FFT), ...

Arduino libraries, like libraries for other programming languages, help easily extend the range of functions available to users in the standard integrated development environment (IDE). They are ...

Flashing LEDs are all well and good, but they’re even better if they can sync up with ambient sounds or music. [mircemk] has built the LUMAZOID visualizer to do just that, relying on some staple maker ...

The Arduino IDE is extremely similar to C++, but judging from the sketches you can find on the Internet, you’d never know it. Simpler Arduino projects can make do with just toggling IO pins, reading ...

The Arduino development team has today announced the availability of a new Arduino IDE in the form of Arduino 1.8.11. The open-source Arduino Software (IDE) makes it easy to write code and upload it ...
