Servo potentio meter control

//including the library that we need to control the servo motor

#include <Servo.h>

//declaring our servo

Servo servo;

void setup() {

//declaring A0 analog pin as input

pinMode(A0, INPUT);

//setting pin 13 as a servo pin, because here we connected our servo

servo.attach(13);

}

void loop() {

//here we are mapping the value of analogRead() from pin A0 (potentiometer)

//this value is between 0 and 1023 and we want to have 0 180 because this

//is the value that servo uses when it is mapped we can write it to servo

//with servo.write()

servo.write(map(analogRead(A0), 0, 1023, 0, 180));

//map function works similiar to smoething like this:

//analogRead(A0)/1023 * 180

//but it has some more advanced features
