Microcontrollers and TRIAC-based dimmers

Introduction
Today, electronics is used in home appliances for applications as widely varying as motor
regulation in a washing machine, control of a vacuum cleaner, dimming of a lamp or heating
in a coffee machine. This evolution has increased pace rapidly because appliances require
enhanced features that are easy to build and modify while electronics-based solutions
become cheaper and more sophisticated.
Within this evolution, microcontrollers (MCU)
