A collection of Arduino tutorial articles, from newest to oldest. These tutorials are compiled from personal to paid projects and university lectures. See Arduino Tutorials page if you want to learn from basics to advanced.
The Arduino simplifies microcontroller programming through easy to use code, software and hardware. The best way to learn Arduino is by building projects so start by trying these Arduino tutorials and improve them!
You can in fact build your own motion sensor without spending too much. Motion sensors can be set up using ultrasonic transceivers, video cameras, or microwave signals. In this tutorial, I’ll show you how to use the PIR motion sensor with a microcontroller. PIR is short for passive infrared which …

Wireless control is much more convenient, especially at a significant distance. Imagine having wires from your controller to your robot! Also, making your project portable is essentially saying making it wireless (unless you still need to plug it on mains). In this tutorial, we’ll look at popular methods for achieving …
