ELECTRONICS PROJECTS FREE CIRCUITS

Introduction

• We found that many engineering students are searching for mini projects on electronics along with circuit diagrams. But they are not able to get the prefect circuit diagrams in the Internet. So, we have decided to publish some of the top electronics mini projects circuit diagrams in this presentation. You may also get the complete circuit information and its applications by visiting the resource links given at the end of each circuit diagram.

• We hope this presentation will be much beneficial to engineering students of ECE, EEE and EIE branches.

1. Water Level Indicator

• Water Level Indicator circuit is a simple mechanism used to detect and indicate the water level in an overhead tank or any other water container.

2. Unbiased Digital Dice with LEDs

• It is a circuit diagram of digital dice which is unbiased. For complete information about this circuit, visit http://www.electronicshub.org/unbiased-digital-dice-with-leds/

3. Automatic Washroom Light Switch

• This circuit automatically turns On the lights when a person enters the washroom and it automatically turns it Off when he leaves it. For more information about this circuit, visit http://www.electronicshub.org/automatic-washroom-light-switch/

4. Automatic Door Bell with Object Detection

• If we install this circuit, it automatically detects the presence of the person and rings the doorbell.

6. Thermistor Temperature Sensing Alarm

• This circuit raises an alarm whenever the temperature crosses a certain limit. For complete information about this circuit, visit http://www.electronicshub.org/thermistor-temperature-sensing-alarm/

7. Hot Water Geyser Controller Circuit

• This circuit is made to turn OFF geysers as soon as our water gets hot and are ready for bathing. For complete information about this circuit, visit http://www.electronicshub.org/hot-water-geyser-controller-circuit/

8. Remote Operated Alarm Circuit

• This circuit rings an alarm when you point a remote at it and press on any button. This can be used as a calling bell to call your assistant. For complete information about this circuit, visit http://www.electronicshub.org/remote-operated-alarm-circuit/

9. Fire Alarm with Siren Sound

• This circuit alerts us when there is a fire accident at home by ringing a siren sound. For complete information about this circuit, visit http://www.electronicshub.org/fire-alarm-with-siren-sound/

10. Water Level Alarm Using 555 Timer

• The aim of this project is to make a water level detecting alarm with simple and low cost hardware without compromising on the performance of the device. For complete information about this circuit, visit http://www.electronicshub.org/water-level-alarm-using-555-timer/
