Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

Pulse Width Modulation is used to vary the pulse-train width. Applications of PWM are speed controllers, limiting power of motors and LEDs. It is a square wave with a varying high and low time. Terms ...

Abstract: This paper presents a simulation of a buck converter using pulse-width modulation (PWM) signal frequencies and duty cycles generated by an Arduino microcontroller for solar panel application ...

When multiple PWM converters are connected in series (or in parallel) in a power electronics circuit, it is appropriate to run all converters at the same frequency but with certain phase shift among ...

Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using the ...

What is PWM (Pulse Width Modulation)? PWM (Pulse Width Modulation) is a technique used to simulate analog voltage levels using a digital output. Instead of varying the actual voltage, PWM rapidly ...
