This isn't a FastLED library discussion, but I think I can point you in the right direction. It looks like you're animationCompleted logic isn't correct. I think it makes sense to move some of that logic out of the shootingStarAnimation() function and put it in the loop() function. I came up with this:
#include "FastLED.h"
#define NUM_LEDS 60 // jumlah LED pada strip
#define PIN 2 // Pin LED
CRGB leds[NUM_LEDS];
unsigned long previousMillis = 0; // Menyimpan waktu terakhir LED diperbarui
int count = 0; // Menyimpan hitungan untuk penambahan hingga NUM_LEDs
//bool animationCompleted = false; // Menyimpan status apakah siklus animasi sudah selesai
void setup() {
//FastLED.addLeds<WS2812B, PIN, GRB>(leds, NUM_LEDS).setCorrection(TypicalLEDStrip); // creates a purple color cast??
FastLED.addLeds<WS2812B, PIN, GRB>(leds, NUM_LEDS).setCorrection(UncorrectedColor);
//FastLED.setMaxPowerInVoltsAndMilliamps(5, 1500); //daya strip LED 5V, 1500mA
FastLED.setMaxPowerInVoltsAndMilliamps(5, 200); //daya strip LED 5V, 200mA
FastLED.setBrightness(8); // dim LEDs
FastLED.clear(); // semua LED menjadi "MATI"
}
void loop() {
unsigned long currentMillis = millis();
if (currentMillis - previousMillis < 10000) { // run star animation for 10 seconds
shootingStarAnimation(255, 255, 255, random(10, 60), random(5, 40), random(2000, 8000), 1);
} else {
turnOnAllLEDs();
previousMillis = currentMillis; // reset timer
count = 0;
}
}
void shootingStarAnimation(int red, int green, int blue, int tail_length, int delay_duration, int interval, int direction) {
count = (count + 1) % NUM_LEDS;
if (direction == -1) { // Opsi arah mundur untuk LED
leds[NUM_LEDS - count - 1].setRGB(red, green, blue); // Atur LED dengan nilai warna
} else {
leds[count].setRGB(red, green, blue); // Atur LED dengan nilai warna
}
fadeToBlackBy(leds, NUM_LEDS, tail_length); // Memudar LED ekor menjadi hitam
FastLED.show();
delay(delay_duration); // Jeda untuk menentukan kecepatan animasi
}
void turnOnAllLEDs() {
// Nyalakan semua LED dengan warna putih
fill_solid(leds, NUM_LEDS, CRGB::White);
FastLED.show();
delay(1000); // show static LEDs for 1 second
}
Thank you for your help, with a few changes to the code you provided, I was able to find the animation form I wanted. my problem is closed, thank you very much
thanks
hiii good evening, sorry to interrupt or maybe on a different path. question, I have a problem with the ws2812b code, maybe here I can help me. using the fastled library. to run several leds with running then static turning them all on for 1 second then to return to the initial loop I had difficulty, it didn't return correctly. here is my code. it's easy to help....
` #include "FastLED.h"
define NUM_LEDS 60 // jumlah LED pada strip
define PIN 2 // Pin LED
CRGB leds[NUM_LEDS];
unsigned long previousMillis = 0; // Menyimpan waktu terakhir LED diperbarui int count = 0; // Menyimpan hitungan untuk penambahan hingga NUM_LEDs bool animationCompleted = false; // Menyimpan status apakah siklus animasi sudah selesai
void setup() { FastLED.addLeds<WS2812B, PIN, GRB>(leds, NUM_LEDS).setCorrection(TypicalLEDStrip); FastLED.setMaxPowerInVoltsAndMilliamps(5, 1500); //daya strip LED 5V, 1500mA FastLED.clear(); // semua LED menjadi "MATI" }
void loop() { if (!animationCompleted) { // Efek animasi shootingStarAnimation(255, 255, 255, random(10, 60), random(5, 40), random(2000, 8000), 1); } else { // Jika animasi selesai, nyalakan semua LED turnOnAllLEDs(); // Set variabel animationCompleted menjadi true agar program tidak masuk ke dalam blok ini lagi animationCompleted = true; } }
void shootingStarAnimation(int red, int green, int blue, int tail_length, int delay_duration, int interval, int direction) { unsigned long currentMillis = millis(); if (currentMillis - previousMillis >= interval) { previousMillis = currentMillis; count = 0; // Reset interval } if (direction == -1) { // Opsi arah mundur untuk LED if (count < NUM_LEDS) { leds[NUM_LEDS - (count % (NUM_LEDS+1))].setRGB(red, green, blue); // Atur LED dengan nilai warna count++; } } else { if (count < NUM_LEDS) { // Opsi arah maju untuk LED leds[count % (NUM_LEDS+1)].setRGB(red, green, blue); // Atur LED dengan nilai warna count++; } } fadeToBlackBy(leds, NUM_LEDS, tail_length); // Memudar LED ekor menjadi hitam FastLED.show(); delay(delay_duration); // Jeda untuk menentukan kecepatan animasi // Jika animasi sudah mencapai akhir, tandai bahwa animasi sudah selesai if (count >= NUM_LEDS) { animationCompleted = true; } }
void turnOnAllLEDs() { // Nyalakan semua LED dengan warna putih for (int i = 0; i < NUM_LEDS; i++) { leds[i] = CRGB::White; } FastLED.show(); } `
