Hi All,
I am having troubles controlling my HS-7950th servo with a push button. My goal is to make the servo rotate 90 degrees when the button is pressed then return to start when the button is not pressed. I am not sure if my issue is in my wiring or the code so I will attach both, also just a note the servo has to be hooked up to an external power supply.
#include <Servo.h>
Servo myservo; // create servo object to control a servo
// a maximum of eight servo objects can be created
int pos = 0; // variable to store the servo position
int button = 2; // The button will be on Pin 7
void setup()
{
myservo.attach(9); // attaches the servo on pin 9 to the servo object
pinMode(pos, OUTPUT);
pinMode(button, INPUT);
digitalWrite (button, LOW);
}
void loop()
{
if (digitalRead(button) == LOW)
for(pos = 0; pos < 90; pos += 90) // goes from 0 degrees to 90 degrees
{ // in steps of degree
myservo.write(pos); // tell servo to go to position in variable 'pos'
// waits 1s for the servo to reach the position
}
if (digitalRead(button) == HIGH)
for(pos = 90; pos>=90; pos-=90) // goes from 90 degrees to 0 degrees
{
myservo.write(pos); // tell servo to go to position in variable 'pos'
delay(50); // waits 50ms for the servo to reach the position
}
}
