Arduino library to manage dimmers compatible with AVR, ESP8266, ESP32, SAMD, and RP2040 platforms.

DIY Arduino consumption regulator build to use excess solar power for auxiliary 'summer' heating. The solar power data are retrieved over SunSpec Modbus TCP. IoT monitoring with Blynk and local Web server.

Firmware for a trailing/leading edge MOSFET/BJT/TRIAC dimmer written in C++ including schematics/PCB-layouts

Esp32-idf zerocrossing library

This device can be used to remotely control the speed of an AC fan and lights to switch it ON/OFF.

Arduino library : control power rate on big AC load with Triac or SSR in safe way without EMI using Bresenham algorithm. Good for big resistive loads.

Generates TRIAC control pulse for soft start of motors used in circular saw and other DIY tools.

A tester device which can measure RPM, Temperature and current of induction motor with overcurrent detection and modular speed controller

Documentation of my changes to the AVR transistor tester

One method of controlling power to AC circuits uses a TRIAC to turn the power on and off at precisely timed intervals that are synchronized with the AC signal.
