Question

Hello, I'm working on a school project using arduino. I'm using a potentiometer to control a brushless motor and so far it works. I was just wondering how to create a dead zone so that the motor doesn't starting spinning the moment I press on the throttle.

My teacher gave me a hint:

if (voltage=>1.5) {

   send out signal;

}

else {

   send out zero;

}

This is the arduino code that I have and it works:

#include <Servo.h> //accesses the Arduino Servo Library

Servo myservo; // creates servo object to control a servo

int val;    // variable to read the value from the analog pin

void setup()
{
myservo.attach(9); // ensures output to servo on pin 9
}

void loop()
{

val = analogRead(1);            // reads the value of the potentiometer from A1 (value between 0 and 1023)
val = map(val, 0, 1023, 0, 180);     // converts reading from potentiometer to an output value in degrees of rotation that the servo can understand
myservo.write(val);                  // sets the servo position according to the input from the potentiometer
delay(15);                           // waits 15ms for the servo to get to set position
}

Thank you in advanced

Explanation / Answer

here is your modified code :---------------->>>>>>>>>>

void loop()
{
val = analogRead(1);            // reads the value of the potentiometer from A1 (value between 0 and 1023)
//use this code for setting deadZone
float volt = val*(5.0/1023.0);
if(volt < 1.5){
    val = 0;
}
val = map(val, 0, 1023, 0, 180);     // converts reading from potentiometer to an output value in degrees of rotation that the servo can understand
myservo.write(val);                  // sets the servo position according to the input from the potentiometer
delay(15);                           // waits 15ms for the servo to get to set position
}
