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.
The SemLab Contactless Liquid Level Sense Module is an open-source, liquid level sensor designed for non-invasive fluid detection. By utilising capacitive sensing, the sensor detects the presence of liquid inside a container or pipeline without making direct contact with the fluid. This non-contact design prevents sensor corrosion, contamination, and degradation…
Missing a visitor at the front door usually means missed package deliveries, keeping friends waiting outside, or missing unexpected guests. Standard doorbells only work if we happen to be sitting nearby and the chime is loud enough to hear. If we are stuck in a work meeting, listening to music with headphones, or away from home, it is easy to miss the ring, leaving…
When an ageing parent falls at home, the immediate injury is usually only half the danger. The real danger begins during the critical time they spend waiting on the floor for help. Lying immobile for extended periods can rapidly lead to severe dehydration, hypothermia, and muscle breakdown, even in homes where family members are regularly around. Expecting an injured…
Almost every kitchen has a pressure cooker, but we've all had trouble handling them. It’s too easy to turn on the stove, get distracted by work, TV, or housework, and forget to turn it off. If we miss a whistle count, food gets burned, utensils get spoiled, and there are chances of accidents in the kitchen. But then again, being in the kitchen and manually counting…
Urban areas are now affected by acoustic disturbances; major Indian cities such as Mumbai, Kolkata, and Delhi rank among the noisiest in the world, driven by dense traffic, construction, festivals, and industrial activity. Extended exposure to these noise levels leads to health issues, including disturbed sleep, increased stress, cardiovascular risk, hearing damage,…
Moving through unfamiliar environments is a challenging thing for visually impaired people. We have a lot of solutions, from sticks to obstacle-avoidance handheld devices on the market, to solve their problem. In the DIY world, a lot of makers have built obstacle-avoidance sticks using Ultrasonic sensors, IR sensors or even a PIR sensor and different variations of…
Digital clocks are one of the most popular Arduino projects, and most of them use traditional seven-segment displays to show the time. While these displays are simple and reliable, they usually have the same familiar rectangular shape and monochrome appearance. When I decided to build a new digital clock for my room, I wanted to create something that worked like a seven-…
Air is a necessity for us human beings, so monitoring it is important. Air quality is monitored in terms of the Air Quality Index(AQI), a single-number scale used to tell how polluted the air is and what health effects it might cause. Particulate Matter is the microscopic solid or liquid which is present in air in the form of dust or smoke. Particulate Matter is the…
"Is it going to rain, or should I leave the windows open?" we would have asked ourselves numerous times. Now the weather is clear, but sometimes the rain will suddenly start pouring. The standard weather forecast application may give you accurate forecasts near the airport or other places, which are kilometres away from us, but it will not give us accurate forecasts…
We can see wall-climbing robots from hobby-level to serious problem-solving ones that are used for inspection, surveillance, cleaning, etc. When we generally talk about robots, a robot can be a firefighting robot, a human-following robot, a self-balancing robot or can be of any type that has some specific features or solves a specific kind of problem. If we talk…
In modern day, the need for surveillance systems is increasing rapidly. We have a lot of recognized brands that offer such solutions. But can we extend the capabilities of a $5 ESP32-CAM module to build something similar?In this project, we are going to build an AI-Based No Parking Alert System using ESP32-CAM, in which, if someone parks their vehicle in front of the…
Industrial automation has revolutionized manufacturing by making production faster, more accurate, and highly consistent. Modern robotic assembly systems combine robotic arms, machine vision, motion control, and embedded control electronics to automate repetitive tasks with minimal human intervention. While these systems are widely used in industries, the same…
