This project implements a closed-loop temperature control system using an Arduino-based PID controller and TRIAC-based AC power control. The system compares multiple temperature sensors (LM35, RTD, ...

Controlling an AC load with an Arduino is simple using either a mechanical relay or a solid-state relay with an optically isolated triac. But dimming an AC lamp is trickier because just limiting ...

AC loads are everywhere around us because at least home appliances are supplied with the mains power. Therefore, we always face the situations that we want to have full control (dimming) over an AC ...
