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 a Barometric Pressure Measuring System using BMP180 and ARDUINO. First of all for interfacing BMP180 to ARDUINO, we need to download a library specifically designed for BMP180. This library is available at: https://github.com/adafruit/Adafruit-BMP085-Library After attaching that library, we can call special functions which…
This LED DIMMER is an Arduino Uno based PWM (Pulse Width Modulation) circuit developed to get variable voltage over constant voltage. The method of PWM is explained below. Before we get start building a 1 Watt LED Dimmer circuit, first consider a simple circuit as shown in figure below.
Now if the…
Humidity and temperature are common parameters to measure environmental conditions. In this Arduino based project we are going to measure ambient temperature and humidity and display it on a 16x2 LCD screen. A combined temperature and himidity sensor DHT11 is used with Arduino uno to develop this Celsius scale thermometer and percentage scale humidity measurement project. In…
To establish a good communication between human world and machine world, display units play an important role. And so they are an important part of embedded systems. Display units - big or small, work on the same basic principle. Besides complex display units like graphic displays and 3D dispays, one must know working with simple displays like 16x1 and 16x2 units.…
Almost every electronic hobbyist must have faced a scenario where he or she must measure the frequency of a signal generated by a clock or a counter, or a timer. We can use an oscilloscope to do the job, but not all of us can afford an oscilloscope. We can buy equipment for measuring the frequency, but all these devices are costly and are not for everyone. With that in…
We all are quite familiar with voting machines, even we have covered few other electronic voting machine projects previously using RFID with 8051, AVR microcontroller, and Raspberry Pi. In this project, we have used the arduino uno board to build a simple electronic voting machine. If you are looking for a similar Fingerprint based biometric voting machine…
In this project we are going to make Clapper circuit using the concept of ADC (Analog to Digital Conversion) in ARDUINO UNO. We are going to use a MIC and Uno to sense the sound and trigger a response. This Clap ON Clap OFF switch basically turns ON or OFF the device, by using the clap sound, as switch. We have previously built Clap switch and Clap ON Clap OFF…
Arduino Uno, the most popular microcontroller among electronics hobbyists and students and its pretty easy to get started with embedded systems using Arduino But one drawback of Arduino is that it needs to be connected to the computer using USB cable to upload the code as it has done have any onboard support for wireless communication. And sometimes, it is very difficult to…
When we are talking about air pollution, dust and smoke are one of the many reasons for air pollution. Not only that, in recent years, due to climate change, wildfires have become more frequent. A recent report from the National Interagency Fire Center (NIFC) reported a total of 58,733 wildfires across the US that had burned more than 7.13 million acres in 2021 alone…
Security is a major concern in our day to day life, and digital locks have become an important part of these security systems. There are many types of security systems available to secure our place. Some examples are PIR based Security System, RFID based Security System, Digital Lock System, bio-matrix systems, Electronics Code lock. In this post, let us build a Secret Knock…
GPS is a very useful device which is used in many electronics projects and applications like vehicle tracking system, GPS Clock, Accident Detection Alert System, traffic navigation and surveillance system etc. But question is how to use the GPS and read the data from GPS? We can easily get the GPS data directly into our computer using Arduino.

Text-to-speech or TTS system converts normal text into Speech. This tech enables the system to speak out the text in a human voice. There are many examples of Text to Speech conversions like the announcements at public transport, the customer care calls, voice assistants in your smartphones, or the navigation menu of any machine. You can even find the TTS in Microsoft Word…
