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.
"Where did my pet go?" If you have a pet, you've probably asked this question at least once. One moment they're playing happily in front of you, and the next... they're gone! Maybe they saw a butterfly, started chasing a bird, or simply decided to go on a little adventure without telling you. A GPS pet tracker solves this problem before it turns into a crisis. Now…
This tutorial shows us how to build our own functional DIY ESP32 metal detector from scratch using an affordable Wi-Fi enabled microcontroller, a handful of easily available electronic components, and a simple, hand-wound copper coil. Instead of relying on expensive, specialised sensors or complex industrial circuits, this PI metal detector circuit project uses…
Most people assume object tracking for autonomous flight is very complex, but it doesn’t have to be that way. All you need is a different way of looking at the problem. We built this project to see if we could make a simple LiteWing drone behave intelligently using just a laptop and a basic camera.By placing the camera above the room ceiling, the floor becomes a…
Robotic arms are widely used in industrial automation, research, and educational projects. Building and controlling one is a great way to learn the fundamentals of embedded systems, motion control, and robotics.
In this project, we will design and build a 4-degree-of-freedom (4-DOF) robotic arm controlled…
Everybody likes weekends. On weekends, you often drive with your family to crowded places like malls, theme parks, or circuses for outings and relaxation. But then comes one of the most frustrating parts of the trip: searching for parking. Sometimes, finding a parking space feels even harder than waking up early in the morning.Even if there is a security guard or…
In the domain of robotics and automation, precision-controlled mechanical movements have ushered in a revolutionary wave across diverse industries, spanning from manufacturing to healthcare. Thanks to the advent of cost-effective microcontrollers (Arduino) and easily accessible programming tools, enthusiasts and hobbyists now have the…
Running, running, every day, we keep running to work, school, and college. In this busy routine, many of us do not even have enough time to eat breakfast properly. Then where do we find the time to clean our homes? Even when we clean, because of laziness or lack of time, we often throw all waste into the same bin without separating biodegradable and non-biodegradable waste. This creates a…
What if a device could see the world the same way humans do, seeing objects, recognizing them, and understanding what they are in real time? Just like our eyes capture visuals and our brain instantly processes them, from bottles and phones to people and everyday items. It will be pretty cool, right? That is exactly what this Raspberry Pi object detection project demonstrates. You can build a…
As adults, it is our duty to follow traffic rules, and the most important rule is to wear a helmet while riding a two-wheeler and not to cross the speed limit. It's not a rule, but it's also for safety. Now, let’s think from the traffic police officer’s side. Their duty is to monitor traffic and check whether everyone is following the rules, but it is quite difficult for a traffic officer to…
Building an indoor positioning system using ESP32 requires technology beyond GPS. While GPS trackers excel outdoors, indoor positioning system needs Ultra-Wideband (UWB) technology to achieve centimetre-level accuracy inside buildings. This guide shows you how to build a complete UWB indoor positioning system using the Qorvo DWM3000 UWB module with ESP32,…
Imagine driving into a crowded parking area and not knowing whether a space is available or not. This project solves exactly that problem by building a smart, automatic parking space detection system using the ESP32-CAM and the CircuitDigest Cloud API. With just a button press, the device captures a real-time image of the parking area and sends it over the internet…
When we see movies, we often see scenes where a villain uses a gun with a face detection system that automatically targets a person accurately. It may look like a very complex technology that is difficult to build on our own, right? Not anymore. Building a face detection system using a Raspberry Pi might sound like something out of a Hollywood thriller, but it…
