Code for 80° Servo:
*************************************************
int servopin=A0;//Define digital interface A0 to connect servo steering gear signal line
int myangle; //Define angle variables
int pulsewidth; //Define pulse width variables
void setup()
{
pinMode(servopin,OUTPUT); //Set steering gear interface as Output
}
void servopulse(int servopin,int myangle) //Define Function
{
pulsewidth=(myangle*11)+500; //Converts the Angle to a pulse width value of 500 - 2480
digitalWrite(servopin,HIGH); //The steering gear interface level is high
delayMicroseconds(pulsewidth); //The microsecond number of the delay pulse width value
digitalWrite(servopin,LOW); //Turn the steering gear interface level to low
delay(20-pulsewidth/1000);
}
void loop()
{
servopulse(servopin,80); //Set steering gear Angle
}
//0 Degree Code:
// servopulse(servopin,0);
