In this guide, we’re going to introduce you to Arduino using the meArm robot arm project as a guide to a variety of skills.

Since the project uses pretty basic components, the Arduino code is equally basic, too. It only has less than 50 lines and easily understandable functions and structures.

The code includes two Arduino libraries: one for the servo and another for the ultrasonic sensors. The main code is a simple 14-line piece with a simple if-else statement you can readily modify.

To celebrate its long-term success, we’ve collected 12 of the coolest, most revolutionary, and most entertaining Arduino projects currently in existence. Prepare to be wowed — and then inspired!

In this article I will add some simple Arduino LED projects starting with basic ones like how to turn on an LED, blinking, and more. Every step will have the code, the schematic, photos of the project ...

An Arduino can be used to test the life of any battery with less than 5 volts, Boxall says. So, for a quick way to see how much juice your AAA, AA, C, or D batteries have left, build this Arduino ...

Walking you through a simple project isn't enough to get a grasp on everything the Arduino can do. Here are some of our favorite tutorials, stores, and forums you can turn to for help.

Some projects are both educational and useful. We believe that [Jasper’s] Arduino based electronic load is one of those project. [Jasper’s] electronic load can not only act as a constan… ...
