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.
Now day’s automation systems are everywhere whether its home, office or any big industry, all are equipped with automation systems. Restaurants/Hotels are also adopting recent automation trends and are installing robots to deliver food and tablets for taking orders. Using these digital menu cards like tablets, customers can easily select the items. This information will…
We are in the Internet of Things (IoT) generation! These days, you can control your home gadgets/devices like air-conditioner, room heater, water heater, etc. remotely from anywhere and the device to do this can easily be built or purchased off the shelf. Over the course, we have also built a few IoT based home automation projects using Arduino, ESP, and Raspberry Pi. But…
Arduino is very popular for building hobby projects and games, and we have previously used Arduino to build Snake game, Ping pong game, Space race game, etc. Today we are building one more popular game using Arduino- Buzz wire game or Steady hand game.
For this project, we will use an Arduino Uno, Buzzer, and two Aluminum wires. A 16x2 LCD is also…
WARNING!! The circuit diagram discussed in this project is only for educational purposes. Be advised that working with 220V AC mains voltage requires extreme precaution and safety procedures should be followed. Do not touch any of the components or wires when the circuit is in operation.
It is easy to turn…
RC cars are always fun to play with, I am personally a big fan of these remote-controlled Cars and have played (still do) with them extensively. Most of these cars today provide a huge torque to handle rough terrains, but there is something that was always lagging, its Speed!!.. So, in this project, we will build a totally different type of RC car…
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…
An oscilloscope is the one instrument every electronics engineer reaches for when a circuit misbehaves. A multimeter tells you a single number, but an oscilloscope shows how a voltage changes over time: the shape of a PWM signal, the bounce of a switch, or the ripple on a sensor output. Bench oscilloscopes are expensive, though, and the best way to understand how one…
MQ series Gas sensors are very common types of sensors used in Gas Detectors to detect or measure certain types of Gases. These sensors are widely used in all Gas related devices like from simple Smoke Detectors to Industrial Air Quality Monitors. We have already used these MQ gas sensors with Arduino to measure some harmful gases like Ammonia. In this article, we will learn…
We all know about accelerometers and gyroscopes; they are primarily used to detect acceleration. While an Accelerometer can measure linear acceleration, the gyroscope can help find the rotational acceleration. A gyroscope is used to measure angular velocity, which uses the Earth’s gravity to determine the orientation of the object in motion. There is a sensor like…
ESP modules are popular for their Wi-Fi functionalities like ESP8266, ESP-12E, etc. These all are powerful Microcontroller modules with Wi-Fi functionalities. There is one more ESP module which is more powerful and versatile than previous ESP modules- its name is ESP32. It has Bluetooth and Wi-Fi connectivity and we already explained BLE capabilities of ESP32 and used ESP32…
Have you ever set an important reminder on your phone only to miss it because the device was in silent mode, left in another room, or buried under tons of notifications? While smartphones have made reminders convenient, they are not always used in every situation, especially for elderly people, students, or professionals with busy schedules.To solve this problem, we…
IoT based devices are getting increasingly popular among us, it is estimated that there will be around 1.5 billion devices connected to the internet by the year 2022. Hence, the engineers of the future are keen to learn how to build IoT devices, supporting that there are numerous development boards to enable quick IoT prototyping. We have used various popular boards…
