Arduino tutorials

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!

Using Rotary Encoders with Arduino

incremental rotary encoder

There exists a sensor for almost all physical parameters. Temperature? Pressure? Weight? Gas Concentration? We’ve written a tutorial for them all on this site. This time, we will try to build a device that measures rotational position. The same device can measure rotational speed too. Of course, we’re talking about the …

Using an E-ink Display with Arduino

e-ink display front

Ever wondered why e-book readers don’t use LCDs, OLEDs, or TFT displays? This is because, with the same usage, e-paper or e-ink displays consume 0.008% power compared to a TFT display. In this article, I’ll be featuring an e-ink display that can be readily used with Arduino and other microcontrollers.

A Guide to Powering your Arduino

Solar-powered Arduino

The Arduino was invented primarily for non-engineers but now, a lot of engineers are also into it. Using it in a fully-developed project is not a good look, yes, but it’s a lot quicker than building from scratch.  My only issue at the beginning is finding the best way to …

Using a Fingerprint Sensor

Sensor attached to Arduino UNO

Fingerprint sensors are old technology but it wasn’t readily available to makers until it was cheap. With such a device, you could easily create a keyless secure lock, biometric attendance system, and many more. Fingerprint Sensor Module I managed to secure a fingerprint sensor module that communicates via TTL serial. …

Arduino State Machine Tutorial

Arduino State Machine Diagram

A finite state machine (FSM) is a theoretical machine that only has one action or state at a time. The machine may go from one state to another if there are inputs (or one input) that triggers the state change. In this article, I will guide you on how to …

How to Use MQ-4 Methane Gas Sensor

MQ-4 methane sensor breakout board

The MQ-4 is one of many gas sensors ready to be interfaced with microcontrollers. Just like the rest of the MQ sensors, the MQ-4 is most sensitive to a particular gas. This time, it’s methane, although the sensor can still detect other flammable gases like butane and propane.

Using AD9833 Signal Generator with Arduino

Arduino AD9833 signal generator

How can you create sine, square or triangular waves with Arduino? Apparently, there’s a way with the help of an IC package — the AD9833. With it, you can now create waveforms for communications, instrumentation, or other similar projects. My tutorial on building your own Arduino AD9833 signal generator after …
