Madis Kaal @ nomad.ee designed a infrared repeater based on ATMEL AVR + TSOP1738 infrared receiver. He writes: I built this MCU based infrared repeater to allow me to control my A/V equipment that is behind a wall. The system is very simple. Power is supplied to CON1 from a cheap...

What is the lowest possible clock frequency at which a microcontroller can still do useful work? Here’s a little project that attempts to explore this weird question. by igendel @ idogendel.com: ATtiny85 runs at 0.000011574Hz clock -...

Update your tinyAVR code to access memories when using 1-series tinyAVRs. Link here (PDF) On tinyAVR® 1-series devices, access to Flash memory and EEPROM has been changed from that on previous tinyAVR devices. This means that existing code for writing to Flash and EEPROM on older...

Creating projects with Arduino can be challenging for kids, this may cause children to lose interest in electronics and DIY projects. The most complicated part is usually the connections required to use a sensor, led matrix or other devices that can be connected to the Arduino (or other...

MATRIX Voice is a"Voice Recognition" development board, designed for the Raspberry Pi or Stand-alone with ESP32 (WiFi/BT/MCU) MATRIX Voice is an open-source VOICE RECOGNITION platform consisting of a 3.14-inches in diameter dev board, with a radial array of 7 MEMS microphones connected...

The STEVAL-FCU001V1 board from ST is designed to support quadcopter drone designers with the latest solutions for motor control, sensors and and microcontroller. A complete sample FW project allows the designer to begin flying small and medium size quadcopters (with brushed or...

Tomu is a programmable computer that is so small that can fit entirely inside a computer’s USB port. It sticks out just a little bit, enough to allow you to press one of the two buttons on it'sy side. It also have two LED lights, to let you know what I’m up to. The project is coming...

ESP32-PICO-KIT V3 is a mini development board based on the ESP32-PICO-D4 SIP module produced by Espressif. All the IO signals and system power on ESP32-PICO-D4 are led out through two standard 20 pin x 0.1" pitch headers on both sides for easy interfacing. The development board...
