A dimmer is just another type of potentiometer. We’ve already explored how to use one to control a servo, but this guide will show how to […]

When the sun goes down, and it starts to get dark in your house, you might need to turn on a few lights to see. But […]

We’ve already explored how to build a robot arm and control it using an ultrasonic sensor. If you want a bit more control (and to learn […]

Hardware stores often sell motion-activated floodlights that you can mount outside your house to turn on whenever someone walks through your yard. However, with an inexpensive […]

Having a quick dial to turn down your computer’s volume is a handy tool that many multimedia keyboards have built in. But if you don’t have […]

Few things you can build with an Arduino are cooler than custom robotics. With just a few servos you can build devices that automate basic mechanical […]

The ultrasonic sensor is a neat, versatile sensor that you can add to your Arduino projects. It uses—as its name implies—ultrasonic sounds to detect when an […]

In a previous guide, we introduced the Arduino Uno and the line of programmable boards and shields based on the platform. But the hardware is nothing […]

In the early 2000s, prototyping electronics was either expensive, complex, or both. That presented a problem for Massimo Banzi and his students at the Ivrea Interaction […]

Introduction Ever wondered how parking sensors work, how your car knows how far you are from colliding with the wall? Ever seen robots avoiding the obstructions […]
