Pin debouncer library for the Arduino platform, to filter out noise on an input pin. This library implements a non-blocking function to detect and filter out random state changes on input pins. The ...

I'm making some PCBs that use the Arduino Uno form factor. I'm planning to make a few of these PCBs, which means I need a lot of pin sockets for these PCBs. As they use the Arduino Uno form factor, ...

There are two kinds of people in the world (and, no, this isn’t a binary joke). People who love the Arduino, and people who hate it. If you’ve ever tried to use a standard prototype board to mount on ...

An RFID-based attendance system transforms the tedious task of manual attendance tracking into an automated, error-free process. What makes this project particularly exciting is how a few inexpensive ...

Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...

Whether you’re an embedded systems vet, high school scientist, or a curious person, you need to start your electronic explorations somewhere. If the manual isn’t enough, then check out this beginner’s ...

A teacher I know is stuck, with only npn transistors in the supply cupboard and the need to create a reversible motor drive for an Arduino project. Reversing ‘bridges’ have four switches (relay ...

A sound sensor is a simple, easy-to-use, and low-cost device that is used to detect sound waves traveling through the air. Not only this but it can also measure its intensity and most importantly it ...
