Simple Mini Projects for ECE and EEE Engineering Students

The following projects are simple mini projects which are commonly used for ECE and EEE engineering students

Implementation of Laser Music System

This laser music system project mainly uses lasers, photocells, IR sensors, and an Arduino microcontroller. This project combines a light sensor system and laser with an IR sensing distance system. This IR sensing distance system senses the user’s hand position when it crosses one or many of the laser beams.

These beams are made observable by a small amount of smoke in a dark room, provide visual guidance to the user to decrease the trouble of using a non-contact instrument as well as enhancing an attractive optical effect for the user. This project uses sharp distance sensors to map the position of the user’s hand to a variable like pitch. The user should move their hand to various heights to attain the desired pitch.

Design and Implementation of an LCD Screen Digital Stop Watch with Microcontroller

Hex file into the microcontroller. The stopwatch comprises two different timing modes such as lap timing and splits timing.

Incoming Call Indication for Mobile

This incoming call indication for mobile is used to escape from the annoyance of mobile rings when you are at home. In this project, when a call comes to the mobile phone, the transmitter inside of the mobile becomes triggered an LED will blink instantaneously. The frequency of this transmitter is around 900MHz.

The L1 coil picks up these oscillations by induction and feeds it to the base of the transistor. This makes the transistor activated and the o/p of the transistor connects to the IC 555 which gets activated and blinks the LED connected to its o/p pin. Thus, when the LED blinks, we can conclude that there is an incoming call close to the circuit.

We can tap the generated energy and produce power by using the speed breaker on the road.

The kinetic energy of the vehicles on the roads can be converted into mechanical energy through the mechanism of rack and pinion. Then, this mechanical energy will be converted to electrical energy using a generator that will be stored in the battery. The energy will save during the day time and that can be used in the night time for lighting the street lights. By using this project we can conserve a lot of electrical energy which can be used in the fulfillment of the future
