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

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.

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

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

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.

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

This is a clone of an SVN repository at svn://mikrocontroller.net/transistortester. It had been cloned by http://svn2github.com/ , but the service was since closed. Please read a closing note on my blog post: http://piotr.gabryjeluk.pl/blog:closing-svn2github . If you want to continue synchronizing this repo, look at https://github.com/gabrys/svn2g

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)

Hobbyist YLFC700 Fan Speed Controller Using a TRIAC

9-channels triac dimmer on Arduino blue Pill with LAN-port, MQTT controlled, HomeAssistant integrated.

Switch light bulbs via MIDI

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

Simple smart room sketch using Relay and Triac.
