Tony Goacher] has worked with a lot of cheap brushless DC motor controllers built in China. They can be very cost-effective, ...

Implement a USB PD protocol analyzer, a USB PD trigger board or a more sophisticated power sink using a few additional components and simple Arduino code. Supports several STM32 microcontrollers.

I built a whole-home ad blocker with a $7 ESP32-S3 board - and it took just minutes ...

I didn't expect to love it, and it has a learning curve, but the possibilities are endless.

Stepper motors use a cogged wheel and electromagnets to rotate the wheel one ‘step’ at a time. Each HIGH pulse sent to the A4988 stepper driver energises the coil, attracting the teeth closest to the ...

In October 2025, Qualcomm acquired Arduino. At that moment, shockwaves ran through the maker community worldwide. 'Arduino is dead,' 'This is the end of open source.' Reddit erupted, and the Hacker ...

ESP32 is a tiny cheap 8$ module with a dual core 32-bit CPU and built in Wi-Fi and dual-mode Bluetooth with sufficient amount of 30 I/O pins for all basic electronics projects. All these features are ...

4. Within the Arduino IDE, select "Sketch" -> "Include Library" -> "Add .ZIP library", then select the downloaded zip file. This should add the library. To use the library, you'll have to include the ...

I wanted to play Game Boy Advance games on the GameCube using a SFC controller, so I built a converter.

Abstract: This research paper presents an automated monitoring system developed with diverse technologies combining cloud computing and Internet of Things (IoT). The system includes motion sensing, ...

[Jean-Christophe Rona] found himself with some free time and decided to finish a project he started two years ago, reverse engineering cheap 433MHz home automation equipment. He hopes to control his ...

In system design, assumptions that facilitate the usual process can lead to highly unsatisfactory performance “off piste”.
