8051 Microcontroller

Pressure sensor MPX4115 interfacing with 8051

MPX4115 a motorola pressure sensor is powered by 5V and delivers output voltage ranging from 0.25V to 4.75V corresponding to pressure 15Kpa to to 115Kpa resprctively.sensor detects pressure produces corresponding voltage which later converted into 8-bit binary number by ADC0804  and passes an accordingly scaled voltage to microcont

Temperature sensor(lm35) interfacing with 8051

The project is built to demonstrate working of LM35 temperature sensor interfaced with 8051 through ADC0804. The LM35 series are precision integrated-circuit temperature sensor produced output voltage (o.o1v per 1° of voltage change) is linearly proportional to the temperature.

Line follower robot(IR based)

line follower robot is machine that can follow a path, a robot that is designed to follow either a black line on white line on the ground without getting off the line.The robot has two ir sensors installed underneath.Left sensor will be controlling left motor Similarly right motor is controlled by right sensor, when the sensor is on black surface motor will be switched on else switched off constantly correcting wrong moves using feedback mechanism forms a simple loop system

Automatic Car Parking System

Now days in many multiplex systems there is a severe problem for car parking systems,So the need is to develop a system which indicates vacant space for parking prior entering.So the project objective is to develop a system to indicate the vacant space as well as eliminate the additional labor cost by automatically control the gate opening and closing.Conventionally, car parking systems does not have any intelligent monitoring systemThis project involves a system including infrared se

Stepper Motor Speed Control via Keypad

in this project you are gonna learn to control both speed and direction of unipolar stepper motor.
