This PWM (pulse width modulation) signal isolation module is built around the widely adopted 6N137 high-speed optocoupler.

Based on the literature survey, we are currently researching and developing the process of controlling the speed and direction of a DC motor using an Arduino Uno microcontroller [7]. It includes an ...

This paper presents Arduino based gate pulse generation technique for firing power electronic switching elements including MOSFET and IGBT. In case of designing an inverter, triggering signal ...

This repository contains examples of bare metal source code for TCD as described in TB3236 - Generating PWM Signals Using TCD with High-Frequency Input document from Microchip. The repository contains ...

A few months ago, [Julian Ilett] found a problem using the Arduino library for PWM. Recently, he revisited the issue and used his own PWM code to fix the problem. You can watch the video below.

The video shows how to use Arduino timers, to create precisely timed events and generate a PWM signal with variable duty cycle.

Three types of PWM signals (blue): leading edge modulation (top), trailing edge modulation (middle) and centered pulses (both edges are modulated, bottom). The green lines are the sawtooth waveform ...

Each channel can be used to generate a completely independent PWM signal directly on hardware. The motivation to develop this library was two fold. First, the current limitation of the Arduino ...
