Arduino SPWM Generator Circuit – Code Details and Diagram

Last Updated on June 9, 2026 by Swagatam 74 Comments

waveform 2

In this post I have explained how to generate sine wave pulse-width-modulation or SPWM through Arduino, which can be used for making a pure sine wave inverter circuit or similar gadgets. The Arduino code is developed by me, and it is my first Arduino code, …and it looks pretty good 🙂 What is SPWM I […]
