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.
The communication protocols are the integral part of a digital electronics and embedded system. Wherever there is interfacing of multiple microcontroller and peripherals, the communication protocol has to be used in order to exchange bunch of data. There are many types of serial communication protocol available. The RS485 is one of the serial communication protocol and is…
Controlling LEDs with voice command seems to be a difficult task, but it’s easy and you can quickly build it. We just need an Arduino UNO to serially communicate with HC-06 Bluetooth module and a smartphone to send voice command to Bluetooth module HC-06. For receiving voice command we are using “Arduino Bluetooth Voice Controller” android app which you can download from…
The ESP8266-01 has been a great module to quench all our thirsts for IOT projects. Since its release, it has developed a strong community and evolved into an easy to use, cheap and powerful Wi-Fi module. Another open-source platform which is much more popular is the Arduino, it already has tons of projects built around it. Combining these two platforms will open up doors for…
In some applications, user input is required to control the functions of a device. There are different kinds of user input methods used in the embedded and digital electronics. The touch sensor is one of them. Touch sensor is an important and widely used input device to interface with a microcontroller and it has made inputting data simpler. There are individual places where…
In previous tutorials, we have covered the basics of FreeRTOS with Arduino and the Queue kernel object in FreeRTOS Arduino. Now, in this third FreeRTOS tutorial, we will learn more about FreeRTOS and its advance APIs, which can make you understand the multi-tasking platform more deeply.
Semaphore and Mutex (Mutual Exclusion) are the kernel objects…
In the previous tutorial, we introduced FreeRTOS in Arduino Uno and created a task for the blinking LED. Now, in this tutorial, we will dive more into advance concepts of RTOS APIs and learn about communication between different tasks. Here we also learn about Queue to transfer data from one task to another and demonstrate the working of queue APIs by interfacing 16x2 LCD…
The OS present inside the embedded devices is called an RTOS (Real-Time Operating System). In embedded devices, real-time tasks are critical where timing plays a very important role. Real-time tasks are Time Deterministic means the response time to any event is always constant so that it can be guaranteed that any particular event will occur at a fixed time. RTOS is designed…
Morse code is a system of communication to encode any character in two different durations of signals called Dots and Dashes. Morse code is developed by Samuel F.B. and further used in telegraphy for transferring secret information. It was most used at the time of World War II. A Morse code can be performed by tapping, flashing light or writing. The Morse code is available…
We all are familiar with the word ‘Automation’, where the human interaction is minimal and things can be controlled automatically or remotely. Home automation is very popular and demanding concept in the field of Electronics, and we are also making our best efforts to make this concept easily understandable and manageable as Electronics Projects. We have previously developed…
Choosing a communication protocol for communication between microcontrollers and peripheral devices is an important part of embedded system. It is important because the overall performance of any embedded application depends on communication means as it is related to cost reduction, faster data transfer, long distance coverage etc.
In the previous…
RFID (Radio Frequency Identification) is an inexpensive and accessible technology. It can be used in many applications such as access control, security, asset tracking, people tracking, etc. You have seen the RFID Door Lock system in Hotels, offices, and many other places where you just have to place the card near RFID reader for a second and the door will be opened. We used…
In this project we are going to interface TCS3200 color sensor with Arduino UNO. TCS3200 is a color sensor which can detect any number of colors with right programming. TCS3200 contains RGB (Red Green Blue) arrays. As shown in figure on microscopic level one can see the square boxes inside the eye on sensor. These square boxes are arrays of RGB matrix. Each of these…
