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.
In this tutorial we are going to design an 8x8 LED Matrix Scrolling Display using Arduino Uno, which will show scrolling alphabets.
8x8 LED Matrix contains 64 LEDs (Light Emitting Diodes) which are arranged in the form of a matrix, hence the name is LED matrix. We are going to make this Matrix by soldering these 64 LEDs on to the perfboard or DOT…
Suppose you are sitting in a room and feeling cold and you want your heater to be automatically turned on, and then off after some time when room temperature is increased, then this project help you to control your home appliances automatically according to the temperature. Here we are controlling Home AC Appliances with Arduino based on the temperature. Here we have used…
In this tutorial we are going to develop a circuit using FLEX sensor, Arduino Uno and a Servo motor. This project is a servo control system where the servo shaft position is determined by the flex or bent or deviation of the FLEX sensor.We have also covered how to interface flex sensor with Arduino, you can also check out that tutorial if intrested.

It’s all started with a small game from the dark ages called “Mario”, right from the time of being a tiny little guy jumping on ducks to save my princess till being a masculine handsome Prince roaming in Persia (Prince of Persia) fighting against darkness to save my world behind I have been a great fan of playing video games and I grew up playing them. But they do get bored…
The Iconic name “Nokia 5110” itself should have bought memories of the robust Nokia mobile phone which was very popular during the 90’s. The model 5110 came with a Graphical Display which was sufficient enough to act as a display screen for the mobile back then. This screen was capable of displaying everything from alphanumeric characters to small graphics that is everything…
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…
“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…
In this tutorial we are introducing concept of ADC (Analog to Digital Conversion) in ARDUINO UNO. Arduino board has six ADC channels, as show in figure below. Among those any one or all of them can be used as inputs for analog voltage. The Arduino Uno ADC is of 10 bit resolution (so the integer values from (0-(2^10) 1023)). This means that it will map input voltages…
Here we are going to establish a communication between an ATmega8 microcontroller and Arduino Uno. The communication established here is UART (Universal Asynchronous Receiver Transmitter) type. It’s serial communication. By this serial communication data can be shared between two controllers, which is a required in various embedded system applications.

In last tutorial, we explained controlling a Robot using Wi-Fi and Arduino, and in this article we are with our next IOT Based Project- RGB LED Flasher using Wi-Fi. Here we have used Arduino and ESP8266 Wi-Fi Module to control the colors of RGB LED, through a Android Phone, over the Wi-Fi.
In this RGB…
Raspberry Pi and Arduino are the two most popular open source boards in Electronics Community. They are not only popular among Electronics Engineers but also among school students and hobbyists, because of their Easiness and Simplicity. Even some people just started liking Electronics because of Raspberry Pi and Arduino. These boards have great powers, and one can build…
In our previous tutorial we learnt how to install python on our windows machine and how to interface Arduino with python using a simple LED control project. If you are new, I would strongly recommend you to fall back to the previous tutorial since this tutorial is a continuation of the same.
You might have already started to wonder why we would need…
