EFFET TRANSITION DOUCE AVEC SHIFT REGISTER

BONJOUR

bonjour ,
Je voudrais savoir comment on peur réaliser un effet de transition douce avec un shift registrer j'ai déjà le programme du shift register qui commande les 8 leds mais je ne sais pas comment on passe du digital à l'analogique ou vice versa voici le rpemeir programme :
// Project 15
//Pin connected to Pin 12 of 74HC595 (Latch)
int latchPin = 8;
//Pin connected to Pin 11 of 74HC595 (Clock)
int clockPin = 12;
//Pin connected to Pin 14 of 74HC595 (Data)
int dataPin = 11;
void setup() {
//set pins to output
pinMode(latchPin, OUTPUT);
pinMode(clockPin, OUTPUT);
pinMode(dataPin, OUTPUT);
}
void loop() {
// turn off the output so the pins don't light up
// while you're shifting bits:

digitalWrite(latchPin, LOW);

// shift the bits out: 0B10001000 sets pins 3 and 7
shiftOut(dataPin, clockPin, MSBFIRST, B00000001);

// turn on the output so the LEDs can light up:
digitalWrite(latchPin, HIGH);
delay (500);

digitalWrite(latchPin, LOW);

// shift the bits out: 0B10001000 sets pins 3 and 7
shiftOut(dataPin, clockPin, MSBFIRST, B00000010);

// turn on the output so the LEDs can light up:
digitalWrite(latchPin, HIGH);
delay (500);

digitalWrite(latchPin, LOW);

// shift the bits out: 0B10001000 sets pins 3 and 7
shiftOut(dataPin, clockPin, MSBFIRST, B00000100);

// turn on the output so the LEDs can light up:
digitalWrite(latchPin, HIGH);
delay (500);
digitalWrite(latchPin, LOW);

// shift the bits out: 0B10001000 sets pins 3 and 7
shiftOut(dataPin, clockPin, MSBFIRST, B00001000);

// turn on the output so the LEDs can light up:
digitalWrite(latchPin, HIGH);
delay (500);
digitalWrite(latchPin, LOW);

// shift the bits out: 0B10001000 sets pins 3 and 7
shiftOut(dataPin, clockPin, MSBFIRST, B00010000);

// turn on the output so the LEDs can light up:
digitalWrite(latchPin, HIGH);
delay (500);

digitalWrite(latchPin, LOW);

// shift the bits out: 0B10001000 sets pins 3 and 7
shiftOut(dataPin, clockPin, MSBFIRST, B00100000);

// turn on the output so the LEDs can light up:
digitalWrite(latchPin, HIGH);
delay (500);

digitalWrite(latchPin, LOW);

// shift the bits out: 0B10001000 sets pins 3 and 7
shiftOut(dataPin, clockPin, MSBFIRST, B01000000);

// turn on the output so the LEDs can light up:
digitalWrite(latchPin, HIGH);
delay (500);

digitalWrite(latchPin, LOW);

// shift the bits out: 0B10001000 sets pins 3 and 7
shiftOut(dataPin, clockPin, MSBFIRST, B10000000);

// turn on the output so the LEDs can light up:
digitalWrite(latchPin, HIGH);
delay (500);
digitalWrite(latchPin, LOW);

}

et le second progrmame pour faire les variations de lumière mais je ne sais pas complier les deux programmes ensemble pour qu'ils fassent touts les actions possibles
merci de m'aider :cry:

int ledPin = 11;
float sinVal;
int ledVal;
void setup() {
pinMode(ledPin, OUTPUT);
}
void loop() {
for (int x=0; x<180; x++) {
// convert degrees to radians
// then obtain sin value
sinVal = (sin(x*(3.1412/180)));
ledVal = int(sinVal*255);
analogWrite(ledPin, ledVal);
delay(25);
}
} :cry:

est ce que quelqu'un peut m'aider car je n'y arrive pas :cry:
