Top 10 Breadboard Projects for Beginners in Engineering

Engineering is an application of various technologies & fields such as designing, innovating, maintaining, creating, controlling and so on. There are various streams in engineering such as electrical and electronics engineering, electronics and communication engineering, computer science engineering, information technology and so on. The projects for engineering students helps to implement their theoretical knowledge practically in developing engineering projects. The project work for EEE & ECE students may include performing electronic experiments. In this article, let us discuss about top 10 breadboard projects for engineering students.

Breadboard Projects

It is always a difficult task to perform electronic experiments, physically and economically as well. Electronic experiments comprise of soldering of components to design electronic circuits which is not economical and also dangerous in case of fault in designing circuits. So, breadboard projects are most economical and easy to check the working of various circuits without soldering the components on the PCB. Hence, these can be called as solderless breadboard projects which can be implemented by connecting various electrical and electronics components on breadboard using connecting wires.

The device used for making a typical louder sound in order to alert and/or attract persons or vehicles is termed as a siren. Generally, siren is used by vehicles such as ambulances, police vehicles, fire vehicles and VIP’s vehicles. Not only for vehicles but siren is also used in many industries, companies, mills, and so on to alert the employees or staff regarding the duty timings.

This breadboard project is a simple and interesting circuit for generating police siren sound using two 555 timers and speaker. To generate siren with frequency around 1KHz a 8Ohm speaker is connected with 555 timers (one 555 timer is connected in astable mode and the other 555 timer is connected in monostable mode for achieving the desired frequency) as shown in the block diagram. The siren sound frequency can be adjusted using the knob in the circuit to match the police siren sound.

Kitchen Timer

The kitchen timer circuit block diagram consists of two LEDs, transistor, 555 timer IC which are connected as shown in the figure. The 555 timer is connected in monostable mode used for triggering first LED which starts an adjustable time period. After completing this time period the second LED will glow. The time period can be adjusted using a preset resistor.

Police Lights

The flashing lights are also typically used by vehicles such as police jeeps, ambulances, fire vehicles, and VIP’s vehicles. The usage of flashing lights is also similar to the siren sound, i.e., for attracting and alerting the people or other vehicles. The police lights project is implemented using simple electronics circuit consisting of two LEDs of different colors.

In general, red and blue colors are used by police vehicles which are capable of solid lighting to attract or alert even from long distances. A 555 timer IC, decade counter, LEDs are used in the project. The decade counter and 555 timer switch the LEDs ON and OFF simultaneously at a high speed for very bright lighting.

Overhead Water Tank Level Indicator

In our day-to-day, typically we observe overflow of water from overhead tank which happens due to lack of maintenance. It is a difficult task to track water level of overhead tank. So, this overhead water tank level indicator is the perfect solution for water overflow & wastage problem, which indicates the level of water in overhead tank.

This breadboard project utilizes water sensors, resistors, and three NPN transistors and LEDs. The insulated copper cables acts as water sensors for analyzing the water level in the tank and the LEDs are switched ON correspondingly to indicate the water level.

Automatic Toilet Delay Lighting

The LED can be turned ON or OFF for a fixed duration using 555 timer IC connected in monostable mode. Thus, the LED turns ON for a few seconds (time period can be increased based on requirement using the adjustable timer) and turns OFF after predefined time duration.

There are more breadboard projects such as Touch Point based Calling Bell, Buzzer based Thermometer for Body Temperature, Discotheque Flashing Light and so on.
