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.
Ultrasonic sensors are great tools to measure distance and detect objects without any actual contact with the physical world. It is used in several applications, like measuring liquid level, checking proximity and even more popularly in automobiles to assist in self-parking or anti-collision systems. Previously, we have also built many Ultrasonic Sensor…
In this project we are going to design a circuit for measuring temperature. This circuit is developed using “LM35”, a linear voltage sensor. Temperature is usually measured in “Centigrade” or “Faraheite”. “LM35” sensor provides output based on scale of centigrade.
LM35 is three pin transistor like device. It has VCC, GND and OUTPUT. This sensor…
In this tutorial we are going to design a 0-99 counter by interfacing two seven segment displays to ATMEGA32A Microcontroller. Here we count events based on number of times button is pressed.
Before moving ahead, let's understand what is a seven segment display. A seven segment display got its name from the very fact that it has seven…
We know in offices, shopping malls and in many other places where only the person with authorization card is allowed to enter the room. These systems use RFID communication system. RFID is used in shopping malls to stop theft as the products are tagged with RFID chip and when a person leaves the building with the RFID chip an alarm is raised automatically. The RFID…
While LPG is an essential need of every household, its leakage could lead to a disaster. To alert on LPG leakage and prevent any mishappening there are various products to detect the leakage. Here we have developed an Arduino based LPG gas detector alarm. If gas leakage occurs, this system detects it and makes an alert by buzing the buzzer attached with the circuit.…
Seven segment displays are important display units in Electronics and widely used to display numbers from 0 to 9. It can also display some character alphabets like A,B,C,H,F,E etc. In this tutorial, we are going to learn how to interface a 7 segment display with 8051 microcontroller. We are using AT89S52 microcontroller from 8051 series.

A line follower Robot is a very simple robot that follows a line, either a black line or a white line. These types of robots are very simple to build and are often the first choice for beginners who are getting started with robotics projects. Basically, there are two types of line follower robots: one is a black line follower, which follows the black line, and the…
The interfacing of a 16x2 LCD display with 8051 microcontroller is very popular and one of the most important in embedded systems programming. This tutorial will explain the complete LCD interfacing of 8051 C program, circuit connections, and coding strategies in a program with the use of the AT89S52 microcontroller.
The display units are the most important output devices in embedded…
Thermometers are useful apparatus that have been used for a long time for temperature measurement. In this project, we have made an Arduino based digital thermometer to display the current ambient temperature on a 16x2 LCD unit in real time. It can be deployed in houses, offices, industries, etc., to measure the temperature. We can divide this Arduino…
LED interfacing is the first thing one would try to do while getting started with any microcontroller. So here in this tutorial, we are going to interface an LED with an 8051 microcontroller, and we will write a C Program to blink the LED. We have used a very popular microcontroller, AT89S52, of the 8051 family, by ATMEL. LED interfacing with 8051 microcontroller…
Whenever we go to vote for elections we come to see electronic voting machines. In this project we are going to design and develop a simple voting machine by using ATmega32A microcontroller. Although we can use the controller to get more than 32 people voting machine, to keep everything simple we are going to make a voting system for a size of four people.We will…
We all know that one of the places where power wastage occurs most in homes and offices is at staircases. We usually turn on light at stairs and leave it in a hurry. In this project we are going to design a stair case lamp which works on battery and only turn on the lights only when someone is present at there. This circuit can be used to save power and it can be used as an…
