Before I start talking about this really cool thing called Arduino (Italian for "good friend"), let me say a few things about the fascinating subject of physical computing. Physical computing has been ...

This program can feed two separate fishtanks simultaneously. The two tanks are called JEFF and BOB. The steps for the stepper motors are calibrated to match the distance in the 3D printable feeder ...

This repository contains Arduino code for obstacle avoidance using an ultrasonic sensor and controlling LEDs based on the measured distance. Connect the positive leg (anode) of each LED to digital ...

In the last installment of The GeekDad Arduino Guide, I introduced you to the Arduino hardware and why it is so cool. Now, let’s start actually using an Arduino. How do you get started? Well, first ...

I had the idea of building this Arduino icicle lights project during the making of the light dimmer circuit and the result can be seen below. Is not a complicated project so it can be done easily by ...

Today, we’re going to explore the uses of addressable LEDs. Addressable LED is an easy way to add complex lighting effects to any project. Each addressable LED has an integrated driver that allows you ...

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led – the green one on the left in the photo. And it has a pair of yellow leds – called TX ...
