Ciao a tutti, ho un problema con il mio intervaluino. Cerco di caricare questo codice

Code:

// Intervaluino
// this code programs the Arduino as an intervalometer for a Canon EOS camera, using two relays and a push button
// this enables you to create time-lapse movies with your camera.
// change the variables “full_time” and “short_time” to automatically calculate the right time interval (based on 25 frames per second)
// upload the code via USB, fire up the Arduino, plug it into your camera’s remote shutter release, and press the Intervaluino push button.
// press the button another time to stop the sequence (doesn’t work that well if your interval is long)
// make sure to turn on single shoot

/////////// Change these variables according to your needs

long full_time = 14400; //full length time to cover (in seconds)
long short_time = 120; //length of time-lapse movie (in seconds)

int shutter_on = 200; //time to press shutter, set between 100 and 300
int shutter_wait = 5000; //initial time to wait to begin sequence
int wakeup = 300; //time to activate wakeup (focus)
int wakewait =200; //time between wake and shutter

/////////// Further Variables ////////////

long shutter_off = (40 * full_time / short_time) – shutter_on – wakeup – wakewait; //time to wait between shutter releases;

int outpin = 11; //output for shutter relay from pin 11
int wakepin = 8; //output for focus relay from pin 8
int switchpin = 2; //input from button from pin 2

int val; //value of button press
int buttonState; //check variable for change of button press
int on_off = 0; //state of sequence (turned on, turned off)

/////////// Setup ////////////

void setup() {
pinMode(outpin, OUTPUT); //outpin gives output
pinMode(switchpin, INPUT); //switchpin receives input
pinMode(wakepin, OUTPUT); //wakepin gives output

buttonState = digitalRead(switchpin); //read value of the button
}

/////////// Loop ////////////

void loop(){

val = digitalRead(switchpin); // read button value and store it in val

if (val != buttonState) { // if the button state has changed…
if (val == LOW) { // check if the button is pressed…
if (on_off == 0) { // if the sequence is currently off…
on_off = 1; // turn the sequence on
delay(shutter_wait); // wait the initial period
} else {
on_off = 0; // turn the sequence off
}
}
}

buttonState = val; //switch the button state

if (on_off == 1) { //while the sequence is turned on…

digitalWrite(wakepin, HIGH); //turn wakeup/focus on
delay(wakeup); //keep focus
digitalWrite(wakepin, LOW); //turn wakeup off
delay(wakewait); //wait
digitalWrite(outpin, HIGH); //press the shutter
delay(shutter_on); //wait the shutter release time
digitalWrite(outpin, LOW); //release shutter
delay(shutter_off); //wait for next round
}

}

Ma mi riporta l'errore

Code:

intervaluino:22: error: stray '\' in program
intervaluino:22: error: stray '\' in program
intervaluino:22: error: stray '\' in program
intervaluino:22: error: expected ',' or ';' before 'u2013'

non so cosa voglia dire. In più in non riesco a caricare lo sketch e mi da l'errore

Code:

Binary sketch size: 1728 bytes (of a 30720 byte maximum)
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

Cosa vuol dire?

Posto qualche foto nel caso fossero utili.
Grazie
