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 ...

The main focus of this project is to create extra channels of 16-bit PWM in the MCU using the available 4 channels of 8-bit PWM on ATmega328P. This is important because high-resolution PWM is ...

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 ...

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 ...

This project uses the Arduino Uno PWM output to realize a fully isolated analog output with a range of 0..5 V or more. The use of an averaged PWM signal is not comparable with a real DAC, but it has ...

The purpose of this project is to provide a 4-20 mA output from a PWM signal generated by a microcontroller. One of the more interesting applications of this circuit would be to replace or to realize ...

A pulse-width-modulated (PWM) signal and the RC-charging characteristics of a weighted-capacitor network can be used along with a CMOS Schmitt inverter to generate a pulse whose width is linearly ...

I am trying to play audio wav. file stored on SD card via PWM. I had two approaches to do it: 1 - Read part of data from SD card via SPI to a buffer. Then, loop through the data and send it to PWM via ...

Yes, you can program Arduino with Python using the PyFirmata library. While Arduino traditionally uses C++ code, Python can control Arduino boards through the Firmata protocol, allowing you to ...
