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

The ESP32 keeps finding new jobs in my house.

ESP32s are surprisingly good AI lie detectors.

The Seeed_Arduino_SSCMA library is designed to enable Arduino hosts to communicate with sensors equipped with the SSCMA-Micro firmware. This library provides the necessary drivers to facilitate ...

Efficient, file reads and writes are direct to FRAM, no caching or background process is used. No fragmentation is possible. All 32bit file operations. The SPI driver is capable of supporting 24bit ...

So here’s the thing: Arduino’s built-in memory is tiny. If you’re just blinking LEDs, no problem. But the moment you try to log data, say battery usage, temperature over time, or GPS coordinates, ...

Arduino has shrunk the UNO R4 with the Arduino Nano R4 board equipped with the same 48 MHz Renesas RA4M1 32-bit Arm Cortex-M4F microcontroller, but offered in a much more compact form factor. It’s ...

Over the last decade, the open-source movement has not only transformed the world of software, but also catalyzed a sweeping revolution in hardware tinkering. At the heart of this shift lies a ...

The Arduino-controlled Drawing Robot is a low-cost pen plotter that can be used to make small drawings on a piece of paper. It is based on an Arduino Nano board with a Bluetooth extension module, ...

Radio Frequency Identification is widely used in contactless payment cards, National Highway Tollgate systems, and in security passes. By integrating an RFID reader with an Arduino, you will be able ...
