Bezeichnungen der LEDs (siehe Datenblatt)

LED1 => PC4
LED2 => PD3
LED3 => PD6
LED4 => PD7

Funktionen der Globalen Variablen

uint8_t mode

0 = links...rechts
1 = rechts...links
2 = Sequenz aus Array
3 = default => alle LEDs an bzw. 1

uint8_t* sequence

Sequenz nach Schema uint8_t*[] = {0, 3, 4, 1, 3, 1, 2, 0};
Nach 4 LED-Moves fängt die Sequenz an der Stelle, wo sie zuletzt war wieder mit LED1 an.

uint16_t delay

Delay der Sequenz in MS.
