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

The digital stopwatch with an LCD display is used to measure the time required for a particular event. This watch is quite different compared with other clocks in many ways  This watch needs much more accuracy than the normal clocks.

This project uses an ATmega8535 microcontroller to control the stopwatch, by which perfect accuracy can be ensured. Here, PonyProg and AVR studio were used to compile the C and loading the. 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.

Low-Cost Fire Alarm System

This fire alarm system project is used to detect a fire and generate an alarm to alert the people in the buildings, offices, and where it is installed. This project uses a BC177 transistor to sense the heat produced due to the fire.

Automatic Plant Watering System

This is one of the most useful projects in the field of agriculture or in homes. The main concept of this project is to water the plants automatically without any human interference. This project is also used in the field of agriculture to watering the crops.

We know that many people in the home, farmers in the agriculture field do not pour the water to the plants, crops when they go on vacation, or often forget to water the plants. As a result, this project is the best solution for these types of problems.

Electricity Generation from Speed Breakers

Day by day, the population is increasing in the entire world and the energy sources are reducing. Therefore, to overcome this problem this project is very useful to generate electricity by utilizing the conventional sources. When a vehicle passes over a speed breaker lots of energy is generated. We can tap the generated energy and produce power by using the speed breaker on the road.

Three Phase Induction Motor Speed Control using PWM Technique

There are various methods to control the induction motor. The stator frequency control is one of the simple methods to control the motor. The microcontroller-based three-phase induction motor speed control system can be used in many industries like cement, textile, chemical to operate the motor according to the speed.

The speed of the induction motor can be controlled by the use of feedback from the motor in terms of rotation per minute (rpm). The inductive magnetic sensor can be interfaced with the microcontroller and the rpm of the motor can be sensed and give to the microcontroller in the form of digital as feedback from the motor.

Simple Mini Projects for ECE Students

Simple mini projects for ECE students include the following.

Simple Mini Projects using 555 Timer

Simple mini projects using 555 timers include the following.

Intruder Alarm using IC 555

The simple circuit like an intruder alarm can be built with IC 555. This circuit generates an alarm once it detects any intruder.

IC 555 based Police Lights

This circuit is used to simulate the lights of the police vehicle. There are two LED lights like red and blue. When the red LED starts blinking, then the blue LED will start flashing immediately. This flashing can be performed continuously.

Sensor Circuit for Reverse Parking

The circuit for reverse parking of vehicles can be designed with IC 555. This circuit helps the vehicle driver while parking the vehicle very securely by specifying the space with the help of three LEDs.
