cool I am getting to know the arduino a little better

this is cool i am getting to know how to use the arduino a little better, though i am still having to use allot of its demos still i am learning how to do some more things. i figured out how to use a pot on a anolog input to control a servo so that is cool.

i hope i can do a few more things like this soon though, and learn how to write the programs from scratch. but i have always had a hard time learning grammer or anything like it. though i can read it and under stand for the most part what it dose, i find it allot harder to write the code in the proper format. but i will learn slowly and bit by bit.

here is the code i used from the demo

// Controlling a servo position using a potentiometer (variable resistor)
// by Michal Rinott  


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

int potpin = 0;  // analog pin used to connect the potentiometer
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(potpin);            // reads the value of the potentiometer (value between 0 and 1023)
  val = map(val, 0, 1023, 0, 179);     // scale it to use it with the servo (value between 0 and 180)
  myservo.write(val);                  // sets the servo position according to the scaled value
  delay(15);                           // waits for the servo to get there
