I’ve been testing out the RYB2340 Bluetooth module, and it’s honestly one of the simplest ways I’ve found to add wireless control to Arduino or ESP8266 projects. In this video, I’ll walk you through ...

It’s always nice to simulate a project before soldering a board together. Tools like QUCS run locally and work quite well for ...

When I wrote about a DIY ESP32-S3 internet radio last week, "raspbeguy" commented he'd rather choose an ESP32-based DIY DAB+ ...

This project demonstrates the interfacing of an Infrared (IR) sensor with the Arduino UNO R4 WiFi to detect obstacles in real-time. It utilizes digital signal processing to monitor the environment and ...

This DIY 6-DOF robot arm project details a two-year build cycle using 3D printed parts, custom electronics, and over 5,000 ...

Minecraft remains one of the best games of all time over a decade on from its release, but spending such a long time in one game could lead to you running out of ideas. We've been there: you've ...

The reinvented 4 isn’t quite so extreme in its pursuit of utility; it doesn’t quite match the original’s 22cm or so of fairly unregulated suspension travel (neither, frankly, would we want it to); and ...

A minimal example that reads a digital IR (obstacle/proximity) sensor on pin D2 and lights the onboard LED (pin 13) when an object is detected. The project is configured to build with PlatformIO for ...
