The blinking LED’s are shown below:. Port 1 of the microcontroller is used as the input Port Port 2 of the microcontroller is used as the output Port The LED’s are connected to the output of Port 2 Two switches are connected to the input of Port 1 one peojects is connected to the 5th pin of the Port 1 whereas the other switch is 89c552 to the 8th pin of the Port 1 Other components like the crystal and switch are used for the working of the microcontroller Working: Proteus is a simulation software which is very essential for every electronics engineers and students as well.

In this article we are going to learn about the interfacing of a Buzzer with the microcontroller. Career advice and jobs related to electronics and IOT. Monday, December 31, Switch S1 is used for turning on the circuit to run the robot. Leave a Reply Click here to cancel reply.


The program for the micro controller is written in C and not projetcs Assembly language. HEX file Please comment if you further want to improve the project or if you have doubts in the above code. Feedjit Feedjit Live Blog Stats. An additional filter circuit, comprising a resistor and a 89cc52 for each IR sensor, is used for preventing interference with noise signals.

Its pin details are shown in Fig.

Normally, the output of the sensor is high. Door Sensor 19 December Feedjit Feedjit Live Blog Stats. This project will give you a clear idea of how to think and imple It drives the stepper motor M1 so that the car changes track to avoid a collision with the obstacle.

User-defined temperature settings are stored in the non-volatile pgojects.

Awesome Timer IC Projects. If you have ever watched the movie”Green Lantern” you will find that the main source of the Hero’s power is his Will Power and As soon as the power is switched on, a high pulse is applied to pin 9 of the microcontroller to reset it. The output of the transformer is fed to bridge rectifier diodes D1 through D4 each 1N Working of each section of the circuit is covered in the following paragraphs Power supply.

When the switch connected to the 5th pin of the micro controller is closed and the switch connected to the 8th pin is open, the micro controller works in the Chasing LED mode i.

Copyright c Microcontroller Projects and Tutorials. Basics, Usage, Parameters and Applications. Switch S2 acts prohects a hardware reset for the microcontroller in case the robot is not running properly. Top 20 Computer Engineering Projects. It is a machine that appears intelligent due to the instructions it receives from a computer inside it which handles multiple tasks.


It is programmed to accept inputs from its port p0 to sense the obstacles around it and control the steering to avoid any collision. Power Bank for Smartphones.

Temperature Indicator using 89c52

The ripple from the output bridge rectifier is filtered by capacitor C1 and fed to regulator IC A resource for professional design engineers. When switch S1 is closed, LED1 glows to indicate the presence of power in the system. The regulated output is given to the temperature sensor, micro controller unit and LCD module, respectively. You might be read Towards the end I ha This low output is sensed by Port 0 of the microcontroller and an action is taken as per preprogrammed instructions.
