Lcd configuration :
void lcd_con() {
Lcd_Config (&PORTD , 1, 3, 0, 4, 5, 6, 7) ; //configure portd as output
LCD_Cmd(LCD_CURSOR_OFF); // send command to LCD (cursor off)
LCD_Cmd(LCD_CLEAR); // send command to LCD (clear LCD)
}
Interrupt :
void interrupt() { CLICHERE FOR MORE INFO
portb.f 2 = 1 ; // Enable the output from dtmf
number = portb ; // register the nalue taken from DTMF
portb.f2=0 ; //Disaple the output from DTMF

Setting Duty from (0-100)%
determines the DC voltage according To this equation :
V = (Duty) * Vdc

MOTOR SPEED CONTROLER | Conclusion
Conclusion :
The necessary code has been made and downloaded in microcontroller
by using2appropriate software. The analog instructions received by the
Section
receiving mobile phone were successfully converted into digital strobes
as interrupt signals to the microcontroller through DTMF The actuation
of the motor is driven by the output ports of the microcontroller.
The proposed work has following advantages :
1) The dc motor can be controlled from anywhere on the globe with
low cost with using more advanced technique .
2) A number of devices can be controlled through a dedicated output
port bits by writing the individual controlling algorithm for each device .
