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.

Esp32-idf zerocrossing library

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

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

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.

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

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.

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

Automatic dimmer for IKEA NYMANE (103.569.62) lamp based on AVR ATtiny13A MCU.

This mirrors the development of the SW from Markus for the ComponentTester (https://github.com/Mikrocontroller-net/transistortester/tree/master/Software/Markus and https://github.com/madires/Transistortester-Warehouse)

Peak detecting transformer inrush current limiter/timer (TRIAC/contactor driver)

Switch light bulbs via MIDI

Simple smart room sketch using Relay and Triac.

This project covers a complete (Home Assistant) smart home solution for single family houses and apartment buildings facing the primarily requirement of replacing the existing high voltage switching system by an I2C-binary sensor system using existing controlling units (like light switches, momentary switches, ..)
