Abstract:
The project aims to design an embedded system which is capable of either increasing/decreasing the speed of the dc motor along with the dc motor direction controlling using IR technology. Here IR transmitter is nothing but a simple TV remote.
Operation:
This project consists of a Microcontroller along with a TV remote, IR receiver, LCD, dc motor and LED indicators. The IR receiver, LCD, LED indicators are interfaced to the Microcontroller. The Microcontroller is programmed using Embedded C language. The Microcontroller is programmed such that whenever the information is received by IR receiver from TV remote, the received information is fed as input to Microcontroller which processes the information and performs appropriate action on dc motor. The percentage increase/ decrease of dc motor speed along with the direction are displayed on the LCD for user reference. To decrease/increase the speed of DC motor a special feature of PIC Microcontroller-PWM (Pulse Width Modulation) is used
Applications:
Industries are using IR solutions for monitoring, process, control, inventory tracking, data links and bar code reading devices.
Commercial wireless applications such as door announcers, security and access systems, gate control, remote activation, score board and paging systems.
Consumer products including electronic toys, home security, gate and garage door openers, intercom, fire and safety systems and irrigation controllers
Bottle filling systems, visitors counter and conveyer application
Advantages:
Speed and direction control from remote place
Speed level and direction display on LCD
Reliable and Easy to operate
