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 ...

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.

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 ...

Arduino is one of those boards that has become synonymous with hacking and making. Since its introduction in 2005, over 700,000 official Arduino boards have been sold, along with untold millions of… ...

Sometimes, the best Arduino projects are the most ridiculous. Case in point, this motion-detecting squirt gun. The idea is simple: when it detects motion, the spray gun activates.

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. The meArm is an open-source kit with all the parts you need to build a ...

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… ...
