B.Tech ECE Mini Projects

List of mini projects.

1. Water Level Alarm Using 555 Timer        
        This is a simple and low cost hardware project using a 555 timer circuit. The aim of this project is to design a water level detecting alarm with simple and low cost hardware without compromising on the performance of the device.

2. Metal Detector Robotic Vehicle
        Land mines buried under the ground causes threat to the lives and affect the economy of the nation. Detection and removing of these mines manually is a dangerous task. So, we use a metal detection robot which works on RF technology.

3. Sun Tracking Solar Panel
        This article describes about circuit that rotates solar panel. This Sun tracking solar panel consists of two LDRs, solar panel, stepper motor and ATMEGA8 Microcontroller.

4 Speed Control of DC Motor Using Pulse Width Modulation
        This pulse width modulation technique is the more efficient way to proceed to manage the speed of our DC motor manually.

5. Bidirectional Visitor Counter using 8051
        This Bidrectional Visitor Counter Circuit is helpful to count the number of persons entering or leaving a room and to display it on a screen.

6. Remote Password Operated Electronic Home Appliances
        This circuit explains you how to control the electrical appliances using an Android device. Here, Bluetooth module is interfaced to 8051 microcontroller. This Bluetooth receives the commands from the Android application device using wireless communication.

7. Simple inverter using IC CD4047
       This simple low power dc to ac inverter (dc to ac converter) circuit converts 12V DC to 230V or 110V AC. By doing simple modification you can also convert 6V DC to 230V AC or 110V AC. It can be used as inverters for home needs to enable light loads (electric bulb, CFL, etc) at the time of electricity failure.

8. SMS Controlled Robot

       GSM controlled robot or SMS controlled robot is a wireless robot which performs the necessary actions by receiving a set of instructions in the form a Short Message Service (SMS).

9. Electronic Eye Controller

       Electronic eye is also called magic eye. As the automation is emerging technology these days, just imagine a door bell that automatically rings when a person visit your home. This also provides security when any person is trying to enter into your home without your permission.

10. Door Knock Alarm

       This is a simple circuit that activates an alarm when there is a knock on the door or there are any vibrations due to movement of heavy goods or furniture. The circuit uses readily available components.
