/* * Servo Move Simple * ----------------- * Move an R/C servo back and forth (0 to 180 degrees) using * delayMicroseconds() for pulse and delay() for time between pulses. * * Created 18 October 2006 * copyleft 2006 Tod E. Kurt * http://todbot.com/ * * Adapted from Daniel @ * http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1160470155/0 * Rotates servo through 180 degrees, using "servoPulse" function * adapted from "Temporary Servo Function" by Tom Igoe and Jeff Gray */ 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 * 9) + 700; // converts angle to microseconds digitalWrite(servoPin, HIGH); // set servo high delayMicroseconds(pulseWidth); // wait a very small amount digitalWrite(servoPin, LOW); // set servo low Serial.print("pulseWidth: "); Serial.println(pulseWidth); delay(20); // refresh cycle of typical servos (20 ms) } void setup() { pinMode(servoPin, OUTPUT); // set servoPin pin as output Serial.begin(19200); } void loop() { // cycle through every angle (rotate the servo 180 slowly) for (myAngle=0; myAngle<=180; myAngle++) { servoPulse(servoPin, myAngle); } delay(1000); }
