Arduino Tutorial

The MPU6050 is a six-axis gyroscope and accelerometer in one package. With its easy-to-use breakout board, it became one of the more popular sensors for the Arduino platform. This article looks into this sensor and teaches how to use it to determine the orientation of an object.

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 …

The 28BYJ-48 stepper motor is a cheap and robust stepper motor, suitable for use on robotics and other slow-speed applications. In this tutorial, I will guide you on how to use this stepper motor with Arduino.

A water flow sensor Arduino project lets you measure how much liquid passes through a tube or pipe. Instead of estimating the water level in a container, the Arduino counts pulses from a flow sensor and converts those pulses into volume and flow rate. In this tutorial, you will learn …

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.

The DHT22 temperature and humidity sensor is a common sensor; in fact, there are tons of tutorials out there teaching you how to use it with your Arduino, Raspberry Pi, or other microcontrollers. What prompted me to write about this sensor is my curiosity about how it gives out two …

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 that can sense hand movements in different directions. Imagine controlling anything just by waving your hands! Let's get …

In control systems, a controller corrects the output of a particular system to a target 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 how …

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, …
