T he ESP32 is a fantastic little microcontroller with a world of possibilities. Its specifications may appear modest, but its capabilities enable it to power all kinds of devices.

This post will give you an Arduino Pixel LED Controller build idea. The inspiration for this post was an old Pixel LED kit I found in my junk box (see the lead image). The locally made kit includes a ...

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...

The code includes two Arduino libraries: one for the servo and another for the ultrasonic sensors. The main code is a simple 14-line piece with a simple if-else statement you can readily modify.

This Cube project uses LED panels for a 3D physics simulation. The creator used ESP32, WS2812b control, and limited external libraries. The source code is available on GitHub, with a possible PCB ...

These days, there’s a huge variety of screens on the market for use with microcontrollers. OLEDs and graphic LCDs abound, while e-ink devices tempt the user with their clean look and low ener… ...
