///////////////////////////////////////////////////// Hello guys,
Speed control of DC motor is a very important thing specially in robotics and other drone making type applications. This video is a detailed tutorial regarding how you can use a joystick to control the speed of a DC motor using PWM pin.

How to setup PIC video link:
   • Setting up a PIC16F877A/PIC16F887/PIC...  

Note: Youtube description dont allow writing greater than and less than mathematical symbols, so for that purpose I am gonna replace
LT = Lesser than symbol
GT= Greater than symbol


MikroC for PIC coding for current video: ( version 7.2.0 )



//////////////////////// Code starts here

float joy;
float per;
void main() {
PWM1_Init(5000); // 5000 = 5KHz
Delay_ms(20);
ADC_Init();
Delay_ms(20);

while(1)
{
joy = ADC_Read(0);
Delay_ms(10);
per = joy / 4; /// it brings ADC value in range of 255 i.e max duty

per = per - 128; //// centre = 512 255/ 2 = 127 per/2;

if ( per LT 0 )
{
per = 0;
}
per = per * 2; /// 0 to 255 is available

PWM1_Start();
PWM1_Set_Duty(per); /// max is 255




}

}
