Smooth Voltage Regulation for LED dimming on 8-bit microcontrollers

Smooth Voltage Regulation for LED dimming on 8-bit microcontrollers

Arduinos can be used as MQTT-enabled LED strip controllers. However, their limited PWM step resolution can pose a problem for the smooth LED lighting look we want to achieve. This post explains the reasons why this happens, explores a cheap and easy solution and provides plenty of reference material to help you come to terms with pulse-width modulation on the Arduino and achieving smooth, seamless, and futuristic LED dimming.
