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.

In this tutorial we are going to control a servo motor by ARDUINO UNO. Servo Motors are used where there is a need for accurate shaft movement or position. These are not proposed for high speed applications. These are proposed for low speed, medium torque and accurate position application. These motors are used in robotic arm machines, flight controls and control systems.…

After designing this line follower robot using arduino uno, I have developed this computer controlled robot. It can be controlled via the computer and we can use specific keyboard keys to move it. It runs over serial communication which we have already discussed in our previous project - PC Controlled Home Automation.

In this tutorial you will learn to make direct connection between your Arduino and Matlab, so that you can program your Arduino directly through Matlab. It is very useful when you are working on complex robotics like Robotic Hand, Humanoid etc. as you can process your complex program on your PC in Matlab and then directly program the results in Arduino.

In this tutorial we will develop a circuit using Force sensor, Arduino Uno and a servo motor. It will be a servo control system where the servo shaft position is determined by the weight present on the force sensor. Before going any further let’s talk about about the servo and other components.

VU Meter or Volume Meter is very popular and fun project in Electronics. We can consider the Volume Meter as an Equalizer, which is present in the Music systems. In which we can see the dancing of LEDs according to the music, if music is loud then equalizer go to its peak and more LEDs will glow, and if music is low then lesser number of LEDs shall glow.…

Arduino is an open-source development platform for engineers and hobbyists to develop electronics projects in an easy way. It consists of both a physical programmable development board (based on AVR series of microcontrollers) and a piece of software or IDE which runs on your computer and used to write and upload the code to the…

In this project we will develop a tone generator using Arduino Uno. We will have buttons interfaced with the UNO and each one of them generates different intensity of tone. The frequency of tone generated by the UNO is same at every internal. It’s the intensity of the sound which changes with each press. This is the one of the easiest way to make a piano with…

In this project we are going to interface 5 RGB (Red Green Blue) LEDs to Arduino Uno. These LEDs are connected in parallel for reducing PIN usage of Uno. 

A typical RGB LED is shown in below figure:

The RGB LED will have four pins as shown in figure.

PIN1: Color…

In this project we will be developing a fun circuit using Force sensor and Arduino Uno. This circuit generates sound linearly related to force applied on the sensor. For that we are going to interface FORCE sensor with Arduino Uno. In UNO, we are going use 8 bit ADC (Analog to Digital Conversion) feature to do the job.

In this project we are going to interface a ROTARY ENCODER with ARDUINO.  ARDUINO UNO is an ATMEGA controller based development board designed for electronic engineers and hobbyists. In ARDUINO we have 20 I/O pins, so we can program 20 pins of UNO to be used as either input or output.

 

A ROTARY ENCODER is used to…

In ARDUINO we have 20 I/O pins, so we can program 20 pins of UNO to be used as either input or output. Although there are more pins on ATMEGA328P controller than on UNO, this is because while designing the board some pins are defaulted.

 

Now for some applications we need more than 30 pins, say if we want to…

ARDUINO UNO is an ATMEGA controller based board designed for electronic engineers and hobbyists. Arduino based program development environment is an easy way to write the program when compared to other environment development programs.
