I am trying to use a hall effect sensor to activate a servo. I want the servo to move to a specific position when the hall effect sensor is activated and then move back when the sensor is deactivated. When I go to the analog read and look at the values I get from the hall effect sensor, the values are 0 when deactivated, but they range from 195-215 when acivated. I think this is why the servo twitches, but im not certain. I think I should have the input read 0 or 1. When he input is 1 the servo should move to this position and move back for values of 0. Can you help me out? Heres the code I have so far
#include <Servo.h>
Servo myservo; // create servo object to control a servo
int inPin = 0; // select the input pin for the Hall Effect Sensorr
int val; // variable to read the value from the analog pin
void setup()
{
myservo.attach(9); // attaches the servo on pin 9 to the servo object
}
void loop()
{
val = analogRead(inPin); // reads the value of the Hall Effect Sensorr (value between 0 and 300)
val = map(val, 0, 300, 0, 20); // scale it to use it with the servo (value between 0 and 20)
myservo.write(val); // sets the servo position according to the scaled value
delay(15); // waits for the servo to get there
