Arduino Uno Projects

This page features a curated collection of Arduino Uno projects designed specifically for beginners and intermediate learners. Arduino Uno is the most widely used board for learning electronics, making it ideal for understanding basic sensors, actuators, and microcontroller programming.

All projects listed here include clear circuit diagrams, Arduino Uno-compatible code, and step-by-step explanations covering real-world applications such as automation, robotics, and IoT fundamentals.

“Sadly, in the name of progress, we have polluted the air, water, soil and the food we eat”. So monitoring the air quality is very crucial now days because of pollution. For designing an air quality monitoring system we need durable and reliable air quality sensor. Although there are many Air Quality parameters but the most important are CO2 and TVOC. So for sensing CO2 and…

A timer is a type of clock used for the measurement of time intervals. There are two types of timer, one which counts upwards from zero, for the measurement of the elapsed time, called as Stopwatch. And, the second one counts down from a specified time duration provided by the user, generally called as Countdown Timer.

Here, in this tutorial we will…

There are many types of LCDs used in Electronic Projects. We have already used 16X2 LCD in many of our projects and also used TFT LCD with Arduino. You can find our entire 16X2 LCD related project by following this link, including interfacing with 8051, AVR, Arduino and many more.

The ST9720 Graphical LCD is totally…

We're building an Arduino automatic pet feeder today that feeds your pet automatically at scheduled times. This complete automatic pet feeder project incorporates a DS3231 RTC (Real Time Clock) Module, allowing you to keep track of your pet's eating schedule and properly schedule feeding at specific times. Our tested design is one of the best pet feeders for DIY makers that…

The first thing that comes in mind when listening to the word Joystick is the game controller. Yes, it’s exactly the same and can be used for gaming purposes. Apart from gaming, it has many other applications in DIY electronics. This joystick is nothing but a combination of two potentiometers for the X and Y planes, respectively. It reads the voltage through the…

We all want our home appliances to be controlled automatically based on some conditions and that's called Home automation. Today we are going to control the light based of darkness outside, the light turns ON automatically when it is dark outside and turns off when it gets bright. For this, we need a light sensor to detect the light condition and some circuitry to control…

We find it difficult to read color codes on resistors to find its resistance. In order to overcome the difficulty of finding the resistance value, we are going to build a simple Ohm Meter using Arduino. The basic principle behind this project is a Voltage Divider Network. The value of the unknown resistance is displayed on 16*2 LCD display. This project also serves as 16*2…

MPU6050 sensor has many functions over the single chip. It consists a MEMS accelerometer, a MEMS gyro, and temperature sensor. This module is very accurate while converting analog values to digital because it has a 16bit analog to digital converter hardware for each channel. This module is capable to capture x, y and z channel at the same time. It has an I2C interface to…

Batteries come with a certain voltage limit and if the voltage goes beyond the prescribed limits while charging or discharging, the life of the battery get affected or reduced. Whenever we use a battery powered project, sometimes we need to check the battery voltage level, whether it is needed to be charged or replaced. This circuit will help you to monitor the voltage of…

Right from the time of industrial age, we mankind have been rapidly developing. With every progress we also pollute our environment and eventually degrading it. Now global warming is an alarming threat and even the air that we breathe are getting critical. So air quality monitoring has also started to gain importance. So in this article we will learn how to use any MQ series…

Programming is always fun and Arduino is a wonderful platform if you are just getting started with Embedded programming. In this tutorial we will build our own calculator with Arduino. The values can be sent in through a keypad (4×4 keypad) and result can be viewed on a LCD screen (16×2 Dot-matrix). This calculator could perform simple operations like Addition, Subtraction,…

LED Blinking is a very common and almost first program for every embedded learner or beginner. In which we blink an LED with some delay. So today we are here with the same project, but here we will use an AC bulb instead of a normal LED and will blink an AC bulb. You can also drive into this project of Relay Interfacing with PIC Microcontroller.
