1. Accelerometer (Gyroscope) Controlled Robot. Accelerometer is mems based 3-axis sensor that can sense the tilt in of the 3-diamentions. The robot moment is controlled based on the tilt angle of the robot. No need to press any buttons for robot control.
2. Password enabled pre-paid liquid/milk dispensing system.
3. RF Control Of Induction/DC/Stepper Motor & Other Industrial Loads
4. uC based Heartbeat Monitoring over GSM Mobile. The design was carried out through the use of two infrared sensors. The sensors check blood density on the patient's fingertips in order to measure heart rate. The raw data from the sensors is processed by microcontroller and the processed data is sent to user over GSM modem/mobile
5. GPS based station name announcement and display system for Trains/buses.
6. Mobile phone controlled Street Light monitoring and control system.
7. Android Smart Phone based Home Automation.
8. GPS & GSM Based Car Security System. Easy to find the stolen Car. Global Positioning Sytem (GPS) has been used in various commercial applications including transportation, navigation and vehicle position tracking, which when coupled with GSM mobile phone technology, the technology can help locate stolen vehicle and retrieval process. (GPS+GSM+Microcontroller).
9. uC based Multiple Device Control based on Change in Input Frequency.
10. Touch Screen GLCD based Digital Devices Control System
11. GSM Mobile phone controlled intelligent Robot.
12. Solar data logger into MMC/SD Memory Card.
