Hoi,
Ik heb deze code :
// Alle pinnen van de leds
const uint8_t ledPins[] = { 9, 11, 10, 6, 3, 5 };
// de pin van de potmeter
byte potPin = A3;
byte switchPin = 12;
// de waarde die de potmeter aangeeft
int potValue;
int switchValue;
bool LED0 = 0;
// geeft de richting aan waar de led moeten draaien.
int richting;
// houdt de index bij van de huidige brandende led
int currentLed = 0;
// houdt de index bij van de leds van de staart
byte trails[5] = {0, 0, 0, 0, 0};
String action;
int oldSwitchValue;
unsigned long previousMillis = 0;
long interval;
void setup() {
// Zet de seriele monitor aan
Serial.begin(115200);
for (uint8_t cnt = 0; cnt < sizeof(ledPins); cnt++) {
// Zet alle leds uit
analogWrite(ledPins[cnt], 0);
// Zet de pin mode op output
pinMode(ledPins[cnt], OUTPUT);
}

Hoe kan ik dit het beste splitsen in classes en misschien wel aparte bestanden zodat het makkelijker is om nieuwe effecten toe te voegen.
JIj gaf me al deze demo.
#define NUMELEMENTS(x) (sizeof(x) / sizeof(x[0]))
// function prototypes
void effect1();
void effect2();
void effect3();
// array with function pointers for effects
void (*effects[])() = {
effect1,
effect2,
effect3,
nullptr,
};
void setup()
{
Serial.begin(115200);
Serial.println("function pointer demonstration");
}
void loop()
{
static uint8_t selected;
if (Serial.available())
{
// read serial data
char ch = Serial.read();
// limit 1..9
if (ch >= '1' && ch <= '9')
{
selected = ch - '0';
}
// make sure that selected effect does not exceed boundary of effect array
if (selected > NUMELEMENTS(effects))
{
Serial.println(F("Ongeldige keuze"));
selected = 0;
}
}
// only if a correct selection was made and an effect function was specified in the effect array
if (selected != 0 && effects[selected - 1] != nullptr)
{
// execute selected function
effects[selected - 1]();
}
}
void effect1()
{
Serial.println(__FUNCTION__);
delay(1000);
}
void effect2()
{
Serial.println(__FUNCTION__);
delay(1000);
}
void effect3()
{
Serial.println(__FUNCTION__);
delay(1000);
}
Misschien kunnen we die als vertrek punt gebruiken.
En jij hoeft niet alles te veranderen.
). Dus moet je uitleggen hoe je meerdere effecten wilt kunnen selecteren en wat die effecten zijn.
