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.
We all know of the wired doorbell systems which require wires and suitable outlets for it to work satisfactorily. As the wired doorbell system needs complicated wiring, it requires an experienced person to get the work done and it does not do good, in both working and appearance. Another problem with it is that, if you want to install a wired doorbell system for an existing…
Are you fed up with manually logging in to your windows or social media accounts? Wouldn’t it be nice to have a pocket-sized device which when connected to a computer would automatically login into all your accounts?
Well probably, you already know about hardware security keys available in the market, but they are not cheap. Furthermore, as far as I…
This project showcases an IoT Weather Station built using the Arduino Uno R4 Wi-Fi, designed to monitor and report various environmental parameters. Utilizing multiple sensors—including the DHT22 for temperature and humidity, the BMP180 for atmospheric pressure, an anemometer for wind speed, a wind vane for wind direction, and a rain gauge for…
Arduino has been a boon for people who are not from the electronics background to build stuff easily. It has been a great prototyping tool or to try something cool, in this project we are going to build a small yet fun Piano using the Arduino. This piano is pretty much plain with just 8 push buttons and buzzer. It uses the tone() function of Arduino to create various types…
This project facilitates real-time remote monitoring of critical health metrics such as heart rate, SpO2, body temperature, and ECG data, which could benefit both patients and healthcare providers. By enabling continuous data transmission to Ubidots, this system provides an accessible and scalable solution for remote health monitoring, which can be particularly…
In India, there are more than 70 lakh wells, that are both Kutcha and Pucca, in the alluvial plain regions. These wells irrigate 38% of the net irrigated area of the country and The traditional homestead type of habitation in Kerala is generally characterized by a well in each compound to tap groundwater. Therefore, it is estimated that the state has around 65 to 70…
As the winter season approaches, comes the festival of lights in INDIA. Yes, we are talking about Diwali, known for lighting up firecrackers. But they don't just light up the party; they also cause air pollution and bring health issues. So, to reduce pollution and improve our health we decided to build an Electronic Firecracker using Arduino which makes a loud sound…
According to the latest data from the National Crime Records Bureau (NCRB), in 2022, India saw 7,435 deaths due to fire accidents. Even though there are a lot of precautions taken for Fire accidents, these natural/man-made disasters do occur now and then. In the event of a fire breakout, to rescue people and to put out the fire, we are forced to use human resources…
Today, we are going to explore the TMC2208, a popular driver module used for controlling 2-phase bipolar stepper motors. Known for its high efficiency and quiet operation, the TMC2208 is designed by Trinamic, a German company that specializes in motion control products. This driver module is widely used in various applications, thanks to its ability to…
Have you ever wanted to control Arduino projects using Python instead of learning C++? You're in the right place! While Arduino traditionally uses C++ like code, you can actually program and control Arduino boards using Python through a powerful protocol called Firmata. This comprehensive guide will show you exactly how to set up Python to communicate with Arduino, control LEDs and sensors,…
QR codes have become essential in our daily lives, from making UPI payments to sharing social media handles QR codes can now be found in almost every shop and business today. Integrating QR code scanning into our projects is a useful and practical feature that enables us to build many exciting projects like smart shopping cart projects, Vending machine projects etc. However, using traditional…
Security is at most concern for anyone nowadays, whether it's data security or security of their own home. With the advancement of technology and the increasing use of IoT, digital door locks have become very common these days. Digital lock doesn’t require any physical key but it uses RFID, fingerprint, Face ID, pin, passwords, etc. to control the door lock. In past, we have…
