 Bigger Bigger  Smaller Smaller  Reset Reset

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   :'(

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);
}
} :'(
