Abstract:
The Embedded Technology is now in its prime and the wealth of knowledge available is mind-blowing. Embedded technology plays a major role in integrating the various functions associated with it. This needs to tie up the various sources of the Department in a closed loop system. This proposal greatly reduces the manpower, saves time and operates efficiently without human interference. This project puts forth the first step in achieving the desired target. With the advent in technology, the existing systems are developed to have in built intelligence.
The main objective of the project titled “EXPLOITATION OF PULSE WIDTH MODULATION FOR DC MOTOR SPEED CONTROL” is the speed control of DC motor which is located in a remote area by means of Pulse-width modulation (PWM) technique. In this project there are two sections one is the transmitter and another one is the receiver section. This paper consists of Power supply, RF-transmitter, RF-Receiver, microcontroller, encoder, decoder, DC motor & driver circuits.
The encoder in the transmitter section consists of Key pad. The data entered through the key board can be encoded and transmitted through the RF transmitter. In the Receiver section the transmitted data can be retrieved by using the RF receiver. According to the data received the microcontroller drives the motor driver unit.
Hardware Requirements:
§ Microcontroller Unit and Power Supply
§ RF Transmitter and Receiver.
§ Motor and driver unit
Software Requirements:
§ Embedded C
§ Keil Compiler
