8051 Microcontroller Projects for Engineering Students

Intel company manufactured the 1st 8-bit 8051 microcontroller in 1981. It was referred to as MCS-51 microcontroller system. ROM,RAM, Timer, Input/output ports, serial communication and interrupt logic all are bulk ink controller. Allaire in built in controller that is why its size was overall small. As we know that when we built a system with the help of microcontroller it always simple and consist of few components. This microcontroller system can be used in various applications to perform a specific operations in machine tools, electronics projects, chemical devices, Medical instrumentation, PC keyboards, automatic cameras etc. In this article we are going to explore some important 8051 microcontroller projects for electronics and engineering students in the field of life.

The modern system contain three main part such as processor which acts as a brain of all system, memory which contains program instructions that tells the system brain what to do and how to do, and input and output that are used for further processing data or output of the data. 8050 Microcontroller can also be used in different engineering projects such as GPS, RFID, GSM, Robotics, Sensor, Android, Voice controlled, and etc.

8051 Microcontroller Projects

The list of some important 8051 microcontroller projects for engineering students includes the following.

1). Electronic Voting Machine (EVM)Using 8051 Microcontroller

The project are keys, LCD Board, and authority switches are the main components are the main components. In this EVM project 3 authority switch’s includes the first is for voting mode selection the 2nd swath is for vote and the 3rd authority switch is for clearing the vote.

2). Password-Based Circuit Breaker using 8051 Microcontroller

This project is for power controller Peron specially. Mostly electrical accidents accrues because of misunderstanding between staff. There project Password based circuit breaker provide the solution to these electrical accidents. A line man can switch on and off by using the password whenever he wants to work with line or power board.
