Um mehrere LEDs ansteuern zu können, wird ein Shift Register zwischengeschaltet. So können Anschlüsse am Arduino-Bord "gespart" werden und dementsprechend mehr LEDs angeschlossen werden. Für Shifting ist wichtig, dass das Binärsystem verstanden wird: das hatten wir doch irgendwann mal in der Primarschule...mittlerweile ist das Wissen wieder aufgefrischt und so kann das Shiftregister via Code angesteuert werden. DOT MATRIX Mit Punkten zeichnen so quasi. Anbei einige meiner Icons.

//SHIFT REGISTER 01

#define LATCH_PIN 8
#define CLOCK_PIN 12
#define DATA_PIN 11

void setup()
{
pinMode(LATCH_PIN, OUTPUT);
pinMode(CLOCK_PIN, OUTPUT);
pinMode(DATA_PIN, OUTPUT);
}

void loop()
{
digitalWrite(LATCH_PIN, LOW);
shiftOut(DATA_PIN, CLOCK_PIN, MSBFIRST, B10000000);
digitalWrite(LATCH_PIN, HIGH);
}

//SHIFT REGISTER 02

#define LATCH_PIN 8
#define CLOCK_PIN 12
#define DATA_PIN 11

void setup()
{
  pinMode(LATCH_PIN, OUTPUT);
  pinMode(CLOCK_PIN, OUTPUT);
  pinMode(DATA_PIN, OUTPUT);
}

void loop()
{
  for(int i = 0; i=1; i--)
  {
  byte myByte = B00000000;
  bitWrite(myByte, i, 1);
  digitalWrite(LATCH_PIN, LOW);
  shiftOut(DATA_PIN, CLOCK_PIN, MSBFIRST, myByte);
  digitalWrite(LATCH_PIN, HIGH);
  delay(100);
  }
}
