pwm.setPWMFreq(1600); // This is the maximum PWM frequency
void loop() {
for (uint8_t pwmnum=0; pwmnum < 16; pwmnum++) {//Incremento para los niveles, en este caso estamos usando 16 canales
for (uint16_t i=0; i<4096; i += 64) { //Este incremento define la velocidad del ciclo, probar con 8,16,32, etc...
pwm.setPWM(pwmnum, 0, i);
//Primer parametro es el LED a encender,
//Segundo: Valor inicial de PWM.
//Tercero: Valor final, en este caso es variable ya que se usa como dimmer
for (uint8_t pwmnum=0; pwmnum < 16; pwmnum++) { //Ciclo para borrar los LEDs
pwm.setPWM(16-pwmnum, 0, 4096 );
