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.
ARDUINO UNO is an ATMEGA controller based board designed for electronic engineers and hobbyists. Arduino based program development environment is an easy way to write the program when compared to other environment development programs.
Components Required
Hardware: Arduino uno board, connecting pins, 220Ω…
In this tutorial we are going to interface a 4x4 (16 key) keypad with ATMEGA32A microcontroller. We know that keypad is one of the most important input devices used in electronics projects. Keypad is one of the easiest ways to give commands or instructions to an electronic system.

After designing this line follower robot using arduino uno, I have developed this computer controlled robot. It can be controlled via the computer and we can use specific keyboard keys to move it. It runs over serial communication which we have already discussed in our previous project - PC Controlled Home Automation.

In this tutorial we are going to interface a 4x2 (8 key) touch keypad with ATMEGA32A microcontroller. We all know keypad is one of the most important input devices used in electronics engineering. This module does not have actual keys, but have specially designed capacitive metal pads, and these pads are very sensitive. So when a person gets in contact with one of…
You must have seen automatic door openers in shopping malls and other commercial buildings. They open the door when someone comes near the entrance and close it after some time. A number of technologies are available to make such kinds of systems, like PIR sensors, Radar sensors, Laser sensors, Infrared sensors, etc. In this Arduino based automatic door…
Servo motors are very useful in electronics and embedded systems. You can find the use of Servo motor everywhere around you, they are used in toys, robots, CD tray of computer, cars, aeroplane etc. The reason of this wide scope is that, servo motor is very reliable and precise. We can rotate it to any particular angle. They are available in wide range, form high torque motor…
Keypad interfacing with 8051 microcontroller represents one of the fundamental skills for embedded systems developers. Matrix keypads are an input device found in calculators, security systems, ATMs, and various industrial control panels. Keypads are widely used input devices in various electronics and embedded projects. They are used to take inputs in the form of …
In this tutorial we are going to discuss and design a circuit for measuring distance. This circuit is developed by interfacing ultrasonic sensor“HC-SR04” with AVR microcontroller. This sensor uses a technique called “ECHO” which is something you get when sound reflects back after striking with a surface.
We know that…
In this project we are going to design a 25V range digital voltmeter by using ATMEGA32A microcontroller. In ATMEGA, we are going to use 10bit ADC (Analog to Digital Converter) to build a digital voltmeter. Now the ADC in ATMEGA can not take a input more than +5V, so for getting a higher range we are going to use a voltage divider circuit.
…
We all are familiar with dice and often played LUDO or SANP SIDI (Snake & Ladders) game by using dice. Dice is a squire type solid box which contains 6 different numbers on all of its sides. We throw dice on a surface to get a random number while playing the games. In this project we have tried to replicate it with a digital dice using arduino uno board. In place of…
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…
If you are looking for a beginners guide on “How to start with 8051 Microcontroller”, here in this article I will show you how to work with 8051 microcontroller practically. I am not going into detail of “What is 8051 microcontroller”, or “How to write a c-program” etc., but the scope of this article is to tell about the hardware and software which are needed to…
