Arduino Tutorial

Arduino tutorials

A collection of Arduino tutorials, from beginning to advanced. These tutorials are compiled from personal to paid projects and university lectures. 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!

Using the 3D Gesture Sensor

3D gesture sensor

I recently got my hands on a 3D gesture sensor from DFRobot and honestly, my brain is ringing with the possible projects I can do with it. Basically, it is a device which can sense hand movements in different directions. Imagine controlling anything just by waving your hands! Let's get …

Arduino PID Control Tutorial

Arduino PID Control Tutorial

In control systems, a controller corrects the output of a particular system to a desired input in the presence of errors and disturbances. The most popular type of controller is PID which is an acronym for Proportional, Integral and Derivative. In this Arduino PID control tutorial, I will show you …

Arduino RFID RC522 Tutorial

Arduino RFID RC522

RFID technology has been around for quite a while. But it was only recently that hobbyist and makers was able to utilize this technology through the Mifare RC522 RFID module. In this article, I will show you how you can easily use cards as keys for anything, from attendance systems, …

Arduino Camera (OV7670) Tutorial

Electronics projects like movement and obstacle detection, drones, and robots require a camera for capturing images. I personally recommend using a Raspberry Pi or BeagleBone Black for these kind of projects because the Arduino doesn’t have enough juice to handle the complexities of pictures and, more so, videos. However, if …

Interrupt Tutorial II - Arduino Timer Interrupt

Arduino Timer Interrupt

On my previous Arduino Interrupt tutorial, I showed how to use the external and pin change interrupts for the ATMega328p-based Arduinos. There, I showed an example where pressing a button halts the normal program execution any time and serves another routine (called ISR). In this article, we’ll look at how …

Arduino Interrupt Tutorial

Arduino Interrupt A0 Pin Change Example

An interrupt, in microcontroller context, is a signal that temporarily stops what the CPU is currently working at. Programming using interrupts is very different from the usual top-to-bottom sequence in an Arduino program and thus can be confusing for some. This article aims to introduce how an interrupt works and …
