2. Magnetic Levitation Circuit

This is an uncomplicated magnetic levitation diagram which hangs up objects at a predetermined distance underneath an electromagnet. The logic or science at the back of it is to supply a magnetic force which is equal & opposite to the force of gravity on the object.

The two forces applied to cancel each other and the object stays hanging in the air. Sensibly this is done by a circuit that decreases electromagnet force when an object comes too nearby and raises it when the object is far out of the range.

3. Anti-collision system for trains

These days several new systems are invented to evade train collisions. This Engineering project is one such way to confine the train collisions. In this project, the microcontroller is united with the GPS modem, GSM modem, or cellular phone. GPS modem will discover the current locations of the train through satellite. The keyboard & display screen are also used with the controller for the convenience of the user.

In this project, a microcontroller is attached with a display (LCD screen), Keyboard, Memory card, and GPS recipient. The particular train will have a GPS recipient with a microcontroller together with a GSM Mobile or Modem.

4. Intelligent load shedding using GSM

Integrating an automatic system in each & every machine is very much required as it helps in saving a lot of time spent on it. In production units where control is maintained over the usage of power i.e. below the predetermined maximum demand,  it is a big hitch.

If the predetermined maximum usage goes beyond the limit, the production units have to give a penalty to the electricity department. Therefore an automation method is necessary to work out the problem. The max demand is defined as the product of the current and the voltage that has been used by the loads.

The significance of the max demand fluctuates for diverse sub-stations depending upon the load. The collective maximum demand is the instant average value of max demand. In this project, the microcontroller is connected with a GSM Modem & RTC. For the convenience of the user, the LCD screen is also connected with the microcontroller. Hence, the critical and non-critical loads are coupled through relays.

5. Tongue Motion Controlled Wheel Chair

TDS (tongue drive system) is a tongue operated unobtrusive supportive technology, which can prospectively give people with brutal disabilities a successful computer accessible and environment-friendly control. It converts users’ intents into commands to control by sensing and categorizing their voluntary tongue movement using a small stable magnet, placed on the tongue, and a collection of magnetic sensors assembled on a receiver outside the mouth. We have developed and applied four control tactics to drive a PWC (a powered wheelchair) using an outside TDS model.

6. GSM Advanced Wireless Earthquake Alarm System for Early Warning

This project explains the system’s structural design for a routing or navigation tool for visually disabled persons using GSM communication. The chief components are a multi-sensory structure (including stereo system vision, auditory range locator, and sensors for movement), a mapper, an alarming mechanism, and a concrete human-machine interface.

Several navigation tools are available for blinds as well, but these tools do not work for local pathfinding, collision avoidance, etc. The main aim of this project research is to develop a wearable device that helps the blind to achieve his local direction-finding tasks.

7. GSM Autonomous CAR Parking

In this project of the car parking system, the entrance of the car is noticed automatically and the entrance of the parking is open for the automobile vehicle. The Car’s number is acknowledged by image development and later the billing is done according to the number of hours the car was parked. RF & IR technology is used for the object’s movement detection at the entrance door and also for data transmission. This car parking project has three sections. The first one is located at the entrance of the parking gate. The next module is positioned in the parking floor. The last one is located in the billing division.

8. Microcontroller Based Two-Axis Solar Tracking System

The foremost objective of this project is to build up and put into practice a model of a two-axis solar track structure based on a microcontroller. The parabolic replicator or parabolic board is assembled approximately two feed diameter to take into custody the sun’s energy.

The parabolic replicator’s focus is to hypothetically calculate an infinitesimally tiny spot to obtain a tremendously high temperature. This two-axis automatically track system has also been developed by bringing into play a microcontroller. The programming language used is an assembly to incorporate the microcontroller of the two-axis solar tracking system.

9. Mobi E-Cops With Multiprocessor System
