In this project, we are going to build an animatronic eye with Arduino. I got the idea to create an animatronic eye while looking for new project ideas online, and this project immediately caught my attention. First of all, it looks cool and has a simple mechanism and I learned a lot about mechatronics while working on this project. A big shout out to Will Cogley for…
While Internet of things (IoT), Industry 4.0, Machine to Machine communication etc are getting increasingly popular the need for wireless communication has become incumbent, with more machines/devices to speak with one another on the cloud. Designers use many wireless communication systems like Bluetooth Low Energy (BLE 4.0), Zigbee, ESP43 Wi-Fi Modules, 433MHz RF…
Sound direction detection is a fascinating concept in robotics and automation. It allows a device to "hear" and determine the direction of a sound. This concept has numerous applications, including robot navigation, smart security systems, gaming, and entertainment. Earlier, we showed you how to measure sound in dB using Arduino. In this tutorial, let's learn how to find the direction of sound…
At the core of the Smart Home Energy Management System is the Arduino UNO R4, which serves as the brain and central hub of this sophisticated energy management solution. The Arduino UNO R4 manages cloud connectivity through Arduino Cloud, allowing it to continuously track and report critical metrics such as battery percentage and historical data. This real-time data…
In this comprehensive TMC2209 Arduino tutorial, we'll walk through a complete example of how to interface a Bigtree Tech TMC2209 stepper motor driver with Arduino UNO for precise directional rotation and step control. This stepper motor driver guide is perfect for beginners looking to learn Arduino stepper motor control using digital signals to move motors…
An RFID-based attendance system transforms the tedious task of manual attendance tracking into an automated, error-free process. What makes this project particularly exciting is how a few inexpensive components can replace expensive commercial systems, giving you complete control over features while learning valuable skills in embedded programming and circuit design…
Most of us would be familiar with the 16×2 Dot matrix LCD display that is used in most of the projects to display some information to the user. However, these LCD displays have a lot of limitations in what they can do. In this tutorial, we are going to learn about OLED displays and how to use them in your Arduino Projects. There are many types of OLED displays available in the market and…
The ATtiny family is a series of one of the smallest microcontrollers in the AVR market. These microcontrollers are capable of utilizing many of the libraries available on the Arduino platform. The ATtiny85 microcontroller chip is 8-pin, 8-bit, AVR microcontroller. Its small size and low power consumption make it a great match for portable projects with small footprints and…
After being inspired by RYNO motors and other self-balancing scooters from Segway, I always wanted to build something of my own Arduino Segway Robot. Thinking for a while, I decided to build a Self Balancing Robot using Arduino. This way I would be able to grasp the underlying concept behind all these scooters and also learn how the PID algorithm works.

If you're looking to add wireless communication to your project, the Arduino nRF24L01 module combo is one of the most reliable and cost-effective solutions available. Whether you're building a DIY spy bug, a long-range walkie-talkie, or just want to control stuff wirelessly, the Arduino nRF24L01 setup gives you the flexibility to send and receive data wirelessly over long distances using the 2…
Agriculture is the backbone of our country and it is very important to know the parameter of soil and water for efficient harvesting. The various parameters that can be monitored are Soil moisture, pH of water, Temperature, etc. We previously measured these parameters in different tutorials but today we will not only combining them but also display them on a webpage so that…
Ever wished your Arduino could send you an SMS alert when something important happens—like an intruder detected by your DIY security system, or a gas leak in your kitchen? With just an Arduino UNO R4 and a few lines of code, you can make that happen—no expensive GSM module required.
In this tutorial, I’ll show you how to send SMS…
