About this document

Arduino TRIAC Phase Control Dimmer by yb3hgf is a document available to read on EtoBox.

This document contains code for controlling a TRIAC phase-angle controller using an Arduino. It defines digital pins and analog inputs for the circuit connections. Interrupt routines are used to detect zero crossings of the AC voltage and trigger the TRIAC at a timed delay after each zero crossing to regulate power to a load. The delay is mapped from an analog sensor input to vary the firing phase angle and control the output voltage.
