Servo myservo; // create servo object to control a servo
void setup()
{
myservo.attach(9,600,2400); // attaches the servo on pin 9 to the servo object
}
void loop()
{
myservo.write(15); // sets the servo position according to the scaled value
delay(2000);
myservo.write(0);
// waits for the servo to get there
}
I have adjusted the delay from 15 to 2000. It doesnt work. I have also used an external power supply to power the servo. What am I doing wrong?
How your servo should be wired and simple servo test code.
// zoomkat 10-22-11 serial servo test
// type servo position 0 to 180 in serial monitor
// or for writeMicroseconds, use a value like 1500
// for IDE 0022 and later
// Powering a servo from the arduino usually *DOES NOT WORK*.
String readString;
#include <Servo.h>
Servo myservo; // create servo object to control a servo
void setup() {
Serial.begin(9600);
myservo.writeMicroseconds(1500); //set initial servo position if desired
myservo.attach(7); //the pin for the servo control
Serial.println("servo-test-22-dual-input"); // so I can keep track of what is loaded
}
void loop() {
while (Serial.available()) {
char c = Serial.read(); //gets one byte from serial buffer
readString += c; //makes the string readString
delay(2); //slow looping to allow buffer to fill with next character
}
if (readString.length() >0) {
Serial.println(readString); //so you can see the captured string
int n = readString.toInt(); //convert readString into a number
// auto select appropriate value, copied from someone elses code.
if(n >= 500)
{
Serial.print("writing Microseconds: ");
Serial.println(n);
myservo.writeMicroseconds(n);
}
else
{
Serial.print("writing Angle: ");
Serial.println(n);
myservo.write(n);
}
readString=""; //empty for next input
}
}
The code that I pasted is simplest in its form . I dont need any user input. All I need is for the servo to move which does not appear to be happening. I have wired up the circuit in the same way. Any ideas?
