lilypad arduino controlling a servo motor

Hello all,

I am planing to use LilyPad arduino to control a servo motor. I tried a simple code but it did nor work. So, i tried using the diecimilla arduino and it worked.

My question is: is it possible to use lilypad to control a servo motor? if yes, do I need anything special in the code to make it work?

The code that I used was:

Servo control from an analog input

The minimum (minPulse) and maxiumum (maxPuluse) values
will be different depending on your specific servo motor.
Ideally, it should be between 1 and 2 milliseconds, but in practice,
0.5 - 2.5 milliseconds works well for me.
Try different values to see what numbers are best for you.

This program uses the millis() function to keep track of when the servo was
last pulsed. millis() produces an overflow error (i.e. generates a number
that’s too big to fit in a long variable) after about 5 days. if you’re
making a program that has to run for more than 5 days, you may need to
account for this.

int servoPin = 10; // Control pin for servo motor
int minPulse = 500; // Minimum servo position
int maxPulse = 2500; // Maximum servo position
int pulse = 0; // Amount to pulse the servo

long lastPulse = 0; // the time in milliseconds of the last pu lse
int refreshTime = 20; // the time needed in between pulses

int analogValue = 0; // the value returned from the analog sensor
int analogPin = 0; // the analog pin that the sensor’s on

void setup() {
pinMode(servoPin, OUTPUT); // Set servo pin as an output pin
pulse = minPulse; // Set the motor position value to the minimum

void loop() {
analogValue = analogRead(analogPin); // read the analog input
pulse = (analogValue * 19) / 10 + minPulse; // convert the analog value
// to a range between minPulse
// and maxPulse.

// pulse the servo again if rhe refresh time (20 ms) have passed:
if (millis() - lastPulse >= refreshTime) {
digitalWrite(servoPin, HIGH); // Turn the motor on
delayMicroseconds(pulse); // Length of the pulse sets the motor position
digitalWrite(servoPin, LOW); // Turn the motor off
lastPulse = millis(); // save the time of the last pulse
