This presentation includes about 10 free electronics projects circuits which are having high demand in present generation. These are mainly helpful for engineering students to get some idea about the projects. We have more than 45 electronics projects circuits in our blog. If anybody interested, then visit http://www.electronicshub.org/mini-projects/
2. 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.
3. 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.

5. 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

6. 4. Automatic Door Bell with Object Detection
• If we install this circuit, it
automatically detects the
presence of the person and
rings the doorbell.

10. 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

12. 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,
