Timed playlist of animations, designed for sequencing and performance.
#include "FastLED.h"

// of animations that automatically rotate on a custom schedule.

// A "ResetPlaylist" method is provided so that the playlist can be
// restarted from a custom external trigger, e.g., a button or event.
// For demonstration purposes, the playlist is reset if the
// sketch receives a letter "r" on the serial port.

The same here :/

I'm trying to put this code:
void bpm()
{
// colored stripes pulsing at a defined Beats-Per-Minute (BPM)
uint8_t BeatsPerMinute = 62;
CRGBPalette16 palette = PartyColors_p;
uint8_t beat = beatsin8( BeatsPerMinute, 64, 255);
for( int i = 0; i < NUM_LEDS; i++) { //9948
leds[i] = ColorFromPalette(palette, gHue+(i2), beat-gHue+(i10));
}
}
to start with pir sensor, not from your playlist. I try to use for my staircase... help me
