Air pollution is a critical concern in modern living environments, particularly in enclosed spaces such as homes, offices, factories, and laboratories, where prolonged exposure to harmful gases ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Abstract: AC- DC motor has been proposed for DC voltage regulation which can be used for DC motor drive, battery charging operations, etc. It's necessary to have a effective power conversion system.

I’ve encountered a limitation when using PWM on the RP2040 with the Mbed-based Arduino core: It seems impossible to set a PWM frequency below ~500Hz. This effectively restricts the usable PWM range, ...

Running out of GPIO pins? Learn how to connect multiple buttons to just one Arduino pin using clever wiring and resistor techniques. Perfect for compact projects, keyboards, or when using small boards ...

Over the last decade, the open-source movement has not only transformed the world of software, but also catalyzed a sweeping revolution in hardware tinkering. At the heart of this shift lies a ...

If you want a good display and interface device for an embedded project, it’s hard to look past an old smartphone. After all, you’ve got an excellent quality screen and capacitive touch interface all ...

Conveyor is a mechanical system used to move goods or materials from one place to another that is carried out continuously. The purpose of this project is to provide education to the wider community ...

If you are thinking of building your very own desktop robot arm and were intrigued by the project published yesterday which took you through the process of creating a mini robotic arm using Arduino.

That’s it, and the built-in LED of my board is indeed blinking now. That was relatively easy to get started, and it may boost the productivity of people preferring to work from the command line ...

Sometimes it’s necessary to drive a resistive load such as an incandescent bulb or heating element from a DC voltage that’s higher than the nominal load voltage. An example would be driving a 6.3-V, ...
