Below section covers a list of simple microcontroller projects to learn and work with the concepts of various microcontrollers and architectures. These microcontroller based projects are covered with detailed explanation of working of hardware, circuit diagrams, software and codes.
Microcontrollers are widely used in various industries, electronic products, automobiles etc.. to perform computing or logical operations. With this huge importance the demand of microcontrollers in industries is prominent and hence as electronics engineers it is important for us to learn how to use them. There are a large number of semiconductor companies manufacturing a variety of microcontrollers, the most popularly ones are 8051 microcontrollers, AVR microcontrollers, PIC microcontroller, TI Microcontrollers, Arduino, Raspberry Pi etc.
Gesture control is one of the coolest ways to interact with technology—no buttons, no touchscreens, just simple hand movements. It almost feels like magic when you can control devices with a wave of your hand!
This technology has a wide range of real-world applications, from flying drones and controlling robots to managing smart home…
In today’s fast-paced world, many of us spend long hours indoors—whether working from home, studying, or just managing our daily routines. Natural cues like changing skies, outdoor temperatures, or the feel of humidity are often lost behind four walls and closed windows. This can make it difficult to stay aware of what’s happening outside, especially when our focus…
Have you ever wanted to build your own IoT-based Weather Monitoring Station? Imagine monitoring real-time temperature, humidity levels, atmospheric pressure, rainfall detection, air quality index (AQI), and more—right from your local network. With the power of the Arduino UNO R4 WiFi, you can create a dynamic weather dashboard web page that displays all your environmental data in real-time…
If you're looking to add wireless communication to your project, the Arduino nRF24L01 module combo is one of the most reliable and cost-effective solutions available. Whether you're building a DIY spy bug, a long-range walkie-talkie, or just want to control stuff wirelessly, the Arduino nRF24L01 setup gives you the flexibility to send and receive data wirelessly over long distances using the 2…
Ever wished your Arduino could send you an SMS alert when something important happens—like an intruder detected by your DIY security system, or a gas leak in your kitchen? With just an Arduino UNO R4 and a few lines of code, you can make that happen—no expensive GSM module required.
In this tutorial, I’ll show you how to send SMS…
Drones rely on various sensors to maintain stable flight, especially when GPS is unavailable or unreliable. One important feature is position holding, where the drone stays in one place without drifting. This is crucial for indoor navigation, hovering, and precision landing. Optical flow sensors, like the PMW3901, help drones achieve this by tracking motion relative…
Walking safely and confidently can be a challenging task for visually impaired individuals, but with the help of technology, we can make it easier for them. This DIY Blind Stick is an innovative yet simple solution that is designed to help users detect obstacles in their path. Using an Arduino Nano, ultrasonic sensor, and buzzer, it can sense objects in their way and…
Focused on versatility and modularity, the LiteWing drone can be programmed and controlled using different platforms. When you purchase a LiteWing drone, it ships with default firmware that supports Crazyflie protocols. This means out of the box, your drone is ready to fly using the mobile application, and also supports cfclient and cflib packages from Crazyflie.
Important…
This GPS tracker using ESP32 should be an exciting project, especially for beginners interested in electronics and software development. It’s a project that brings childhood curiosity about tracking everything around us to life. While the hardware setup is relatively simple, the real challenge lies in the software. But that’s no longer a concern, thanks to the…
Looking to add motion control to your Arduino projects? Whether you're building a robot, conveyor system, remote-controlled car, or any other motorized project, controlling motor speed and direction is essential. The L298N Motor Driver Module is a powerful and cost-effective solution for driving DC motors and stepper motors with…
Have you ever noticed how shopping malls, parking lots, or event venues seem to track the number of people or cars present inside? You might think they use an AI camera to count them, but in reality, a simple sensor based system can efficiently accomplish this task. By placing sensors at a single entry/exit point, these systems can detect movement direction and track…
This ESP32 project is an exciting and interactive way to control LEDs using hand gestures. We will use an ESP32 board, Python, MediaPipe, and OpenCV to create a system that can detect specific hand gestures and translate them into actions that control LEDs. MediaPipe will be used to recognize the hand gestures, while OpenCV will capture the real-time video feed from a webcam. Based on the…
