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!
Last time, I showed how easy it is to detect colors using the Pixy2 camera. However, the camera’s price might be too expensive for some. Luckily, there is a much cheaper option to implement an Arduino color sensor. The color sensor I’m referring to is the TCS230 (and equivalent TCS3200) …

Unlike stepper and servo motors, precision control for DC motors is impossible unless a sort of feedback mechanism is employed. If your application requires a consistent motor speed or a stimulant-dependent speed then you certainly need feedback. This tutorial aims to develop a simple motor speed sensor for a more …

How do you measure the volume of a liquid? There are a couple or so ways to do it. One technique is to determine the level of the liquid in a container with a known cross-sectional area. For level measurements, an ultrasonic sensor is useful. Another technique is to use …

The basic Arduino boards are not powerful enough for image processing. Heck, they are not even good enough to capture photos without the help of a desktop computer. However, there is a special imaging device you can use to make an Arduino detect objects.
