A true engineer is one who is not only theoretically proficient but has the ability to implement this knowledge to solve critical problems. In order to become a valuable engineer, there are some skills which are absolutely necessary. Besides having theoretical knowledge, an engineer is also supposed to be proficient in practical and technical skills. Consequently, mini projects are one of the best ways to gain important practical skills. Therefore, in this article we will explore the Ultimate Mini Projects for ECE students.
- Skills and knowledge.
- Embedded systems.
Line following robot
The line follower robot is an automated mobile robot. This robot follows a particular specified path. Incidentally, the path may be a black line on white surface or vice versa. The major components required for line following robot are Arduino UNO, RF sensors, motor, and motor driver IC. Line follower robot has many applications such as in automobiles, industrial applications, human services etc.
Obstacle avoiding robot
Another easy mini project on robotics is the obstacle avoiding robot. The obstacle avoiding robot steers clear from hurdles and avoids collision with them. The major components required for obstacle avoiding robot are Arduino UNO, motors, motor driver, and ultrasonic sensors. Obstacle avoiding robot can be implemented in household uses and navigation systems.
Microcontroller based mini projects
Water level controller
The water level controller is a great project to make use of your technical skills for a good purpose. The wastage of water from overhead tanks is a common issue. Thus, water level controller is an automated project which can sense and control the level of the water in water tanks. The main components of this mini project are AT89C51 Microcontroller and sensor probes to detect the water level.
The digital voltmeter measures the voltage difference between two points in a network. this voltmeter can be designed using AT89C51 microcontroller, IC, and a battery. Consequently, this is a great mini project to measure voltage difference in very low voltage applications.
Automation based mini projects
Automated light intensity controller
Automated light intensity controller is a great mini project to reduce electricity wastage. This intensity controller uses Arduino UNO, LEDs, and a Light Dependent Resistor or LDR. As a result, this mini project can control the intensity of light by turning it ON or OFF.
Automated smoke detection system
The automated smoke detector is a great mini project for beginners or students. The idea behind this project is that the output voltage of the sensor varies in accordance to the level of the smoke in the room or the area. The smoke detector consists of Arduino UNO, LEDs, and a smoke detection sensor. Moreover, the circuit uses a buzzer to alert whenever the level of smoke increases in a particular area.
Automatic irrigation system
The purpose of this mini project is to reduce the human labor in the irrigation task. Furthermore, this system also makes sure that proper irrigation is carried out on the fields. The major blocks of the automatic irrigation system are microcontroller, soil moisture sensor module, motor, and a crystal oscillator. Accordingly, this automatic system is used to turn the water pump ON or OFF by sensing the moisture content in the soil.
Creative mini projects
Weekly task alerting system
The task alerting system is a great project to keep track of all the tasks and appointments made by the user. It comprises of components such as counter IC, power supply or battery, LEDs and Buzzer. Consequently, This mini project alerts the user regarding his/her appointments at the specific time on specific days.
SCR based battery charger-
SCR (Silicon Controlled Rectifier) or a thyristor is a four-layer unidirectional current controlling device. A battery charging system can use the SCR as a rectifier. A step down transformer is connected to the AC source. Then, It is given to the SCR after converting large AC source to limited AC source. Finally, The resulting voltage is given to the battery for charging purpose.
Smart burglar alarm
The safety of important documents, objects, money, and other items is the prime concern for any individual or an organization. Furthermore, people are continuously worried regarding the security of their possessions. This smart burglar alarm consists of PIR sensor, IC, transistor, battery, and a buzzer. Hence, the smart burglar alarm is a great way to alert an individual whenever there is a sign of an intrusion.
Digital heartbeat monitor
Another mini project built for a good purpose is the digital heartbeat monitor. The major components of this mini project are AT89C51 microcontroller, crystal oscillators, power supply, LCD, and most importantly, a heartbeat sensor. Hence, this project is a simple way to monitor the heartbeat rate of the patient.
