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 ...

Using an arduino uno plugged into my desktop, I set up a circuit using the diagram in Circuit.pdf. Use a breadboard or similar to wire it up and it works :) Make sure the ground is common but 12/24V ...

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 ...

I made this Arduino project that allows to turn ON and OFF LEDs using a cheap IR remote control as a preparation for the next big step: disassemble my girlfriend’s chinese LED lamp and replace its ...

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 ...

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 ...
