Ciao a tutti, rieccomi qua dopo vari progetti e più esperienza, ma non riesco a fare questo:
ho n strisce led, su una faccio andare su e giù dei colori, la seconda blink rosso etc. In pratica ogni striscia può avere un suo effetto. Il problema è che nel loop {} passo da un effetto all'altro , in pratica finisce il primo e poi va al secondo e di conseguenza il primo si ferma.
Qeesta è la parte del codice loop
//striscia 0
for(int a=0;a<100;a++){
animationA();
animationB();
uint8_t ratio = beatsin8(2); // Alternate between 0 and 255 every minute
// This inner loo= p will go over each led in the current strip, one at a time
for(int i = 0; i < NUM_LEDS_PER_STRIP; i++) {
leds[0][i] = blend( leds2[i], leds3[i], ratio );
}
FastLED.show();
}
//striscia 1
for(int a=0;a<100;a++){
animationA();
animationB();
uint8_t ratio = beatsin8(2); // Alternate between 0 and 255 every minute
// This inner loop will go over each led in the current strip, one at a time
for(int i = 0; i < NUM_LEDS_PER_STRIP; i++) {
leds[1][i] = blend( leds2[i], leds3[i], ratio );
}
FastLED.show();
}
//striscia 2
for(int a=0;a<100;a++){
animationA();
animationB();
uint8_t ratio = beatsin8(2); // Alternate between 0 and 255 every minute
// This inner loop will go over each led in the current strip, one at a time
for(int i = 0; i < NUM_LEDS_PER_STRIP; i++) {
leds[2][i] = blend( leds2[i], leds3[i], ratio );
}
FastLED.show();
}
// seguirebbero le altre striscie
//altri effetti
coloriinlinea();
}
//END LOOP
Praticamente striscia0 va a completamento(for a),poi parte stricia1 etcc. Io vorrei che stricia0 continuasse a fare l'effetto poi(dopo il ciclo for a) partisse striscia1 e che striscia0 continuasse, poi parte striscia2 e striscia 0 e 1 continuassero e così via.
Invece parte striscia1 e striscia0 si ferma (ed è corretto perchè il loop lavora così), ma non so come fare quanto vorrei!
