Arduino Simple Servo code

int servoPin = 7; // R/C Servo connected to digital pin
int myAngle; // angle of the servo (roughly in degrees) 0-180
int pulseWidth; // function variable

void servoPulse(int servoPin, int myAngle) {
pulseWidth = (myAngle * 11) + 500; // converts angle to microseconds
digitalWrite(servoPin, HIGH); // set servo high
delayMicroseconds(pulseWidth); // wait a very small amount
digitalWrite(servoPin, LOW); // set servo low
delay(20); // refresh cycle of typical servos (20 ms)

void setup() {
pinMode(servoPin, OUTPUT); // set servoPin pin as output

void loop() {
// cycle through every angle (rotate the servo 180 slowly)
for (myAngle=0; myAngle<=180; myAngle++) {
servoPulse(servoPin, myAngle);
