Tony Goacher] has worked with a lot of cheap brushless DC motor controllers built in China. They can be very cost-effective, ...

Providing power via contact-closure circuits historically required a new third wire, but perhaps no longer. Say the words “solid-state relay” (SSR) and most engineers also naturally think of two ...

While there is a time and place for wirelessly controlled devices, sometimes you want something you can just reach out and ...

This tutorial covers the basics of ESP32's built in pulse width modulation(PWM), N-channel MOSFET, and goes over how to control the power output of a supply such as battery or USB port bank using PWM ...

Abstract: Compared with the widely used constant switching frequency pulse-width-modulation (PWM) method, variable switching frequency PWM can benefit more because of the extra freedom. Based on the ...

Stepper motors use a cogged wheel and electromagnets to rotate the wheel one ‘step’ at a time. Each HIGH pulse sent to the A4988 stepper driver energises the coil, attracting the teeth closest to the ...

Abstract: This paper first starts with reviewing several commonly practiced PWM schemes for the three-phase isolated buck matrix-type rectifier. Then, an optimal six-segment PWM scheme (“Type A”) is ...

This library provides a simple device independent interface for interacting with Adafruit IO using Arduino. It allows you to switch between WiFi (ESP8266, ESP32, ESP32-S2, ESP32-S3, ESP32-C3, RP2040, ...

This page features a curated collection of Arduino Uno projects designed specifically for beginners and intermediate learners. Arduino Uno is the most widely used board for learning electronics, ...
