2.2 Definition of a Microcontroller Microcontroller‚ as the name suggests‚ are small controllers. They are like single chip computersthat are often embedded into other systems to function as processing/controlling unit. For example‚ the remote control you are using probably has microcontrollers inside that do decodingand other controlling functions. They are also used in automobiles‚ washing machines‚microwave ovens‚ toys ... etc‚ where automation is needed.The key features of microcontrollers include:

Executive Summary The objective of the project was to create a circuit with an 8051 microcontroller that senses when an object passed through an infrared receiver’s receive path to automatically turn on lights and count how many times the receive path was blocked. 2. Introduction Digital visitor counter is a reliable circuit

Solar seeker: In this project we design a solar seeker to follow a sun. solar seeker follow the sun and if the sensor attach on the sensor a sense a sun then solar seeker is stop automatically. Now after some time sun move from its position‚ then again seeker sensor sense the light and move the motor very slowly. If the sensor sense the signal then automatically stop the seeker . Movement of the seeker is restricted from left to right for limited area. To control the left and right limit

WIRELESS ACCIDENT INTIMATING SYSTEM USING RF The main aim of this project is to implement a system to identify accident by using wireless communication technology RF. The purpose of the project is to get information about the crashing of particular vehicle which passing through a remote area‚ and using sensor and transmitting a message to the concerned receiver section by using RF communication. In present days Electronic communication takes an important role. In this project we are sending
