Bonjour je suis débutant dans ce domaine et je souhaite réaliser/modifier un projet existant qui vous paraitra certainement simple pour vous, mais tellement compliqué pour moi.
j'utilise 4 arduino qui gèrent un ruban led chacun avec une led qui descend a une vitesse et une couleur différente. L'idée se serait d'utiliser un seul Arduino Méga ou autre pour gérer tout ça.
J'utilise ce code trouvé sur internet que je cherche a modifier mais je ne m'en sors pas...
// Use if you want to force the software SPI subsystem to be used for some reason (generally, you don't)
// #define FASTLED_FORCE_SOFTWARE_SPI
// Use if you want to force non-accelerated pin access (hint: you really don't, it breaks lots of things)
// #define FASTLED_FORCE_SOFTWARE_SPI
// #define FASTLED_FORCE_SOFTWARE_PINS
#include <FastLED.h>
///////////////////////////////////////////////////////////////////////////////////////////
//
// Move a white dot along the strip of leds. This program simply shows how to configure the leds,
// and then how to turn a single pixel white and then off, moving down the line of pixels.
//
// How many leds are in the strip?
#define NUM_LEDS 60
// Data pin that led data will be written out over
#define DATA_PIN 3
// Clock pin only needed for SPI based chipsets when not using hardware SPI
//#define CLOCK_PIN 8
// This is an array of leds. One item for each led in your strip.
CRGB leds[NUM_LEDS];
// This function sets up the ledsand tells the controller about them
void setup() {
// sanity check delay - allows reprogramming if accidently blowing power w/leds
delay(2000);
// Uncomment one of the following lines for your leds arrangement.
// FastLED.addLeds<TM1803, DATA_PIN, RGB>(leds, NUM_LEDS);
// FastLED.addLeds<TM1804, DATA_PIN, RGB>(leds, NUM_LEDS);
// FastLED.addLeds<TM1809, DATA_PIN, RGB>(leds, NUM_LEDS);
FastLED.addLeds<WS2811, DATA_PIN, RGB>(leds, NUM_LEDS);
// FastLED.addLeds<WS2812, DATA_PIN, RGB>(leds, NUM_LEDS);
// FastLED.addLeds<WS2812B, DATA_PIN, RGB>(leds, NUM_LEDS);
// FastLED.addLeds<NEOPIXEL, DATA_PIN>(leds, NUM_LEDS);
// FastLED.addLeds<APA104, DATA_PIN>(leds, NUM_LEDS);
// FastLED.addLeds<WS2811_400, DATA_PIN, RGB>(leds, NUM_LEDS);
// FastLED.addLeds<GW6205, DATA_PIN, RGB>(leds, NUM_LEDS);
// FastLED.addLeds<GW6205_400, DATA_PIN, RGB>(leds, NUM_LEDS);
// FastLED.addLeds<UCS1903, DATA_PIN, RGB>(leds, NUM_LEDS);
// FastLED.addLeds<UCS1903B, DATA_PIN, RGB>(leds, NUM_LEDS);
// FastLED.addLeds<WS2801, RGB>(leds, NUM_LEDS);
// FastLED.addLeds<SM16716, RGB>(leds, NUM_LEDS);
// FastLED.addLeds<LPD8806, RGB>(leds, NUM_LEDS);
// FastLED.addLeds<P9813, RGB>(leds, NUM_LEDS);
// FastLED.addLeds<APA102, RGB>(leds, NUM_LEDS);
// FastLED.addLeds<DOTSTAR, RGB>(leds, NUM_LEDS);
// FastLED.addLeds<WS2801, DATA_PIN, CLOCK_PIN, RGB>(leds, NUM_LEDS);
// FastLED.addLeds<SM16716, DATA_PIN, CLOCK_PIN, RGB>(leds, NUM_LEDS);
// FastLED.addLeds<LPD8806, DATA_PIN, CLOCK_PIN, RGB>(leds, NUM_LEDS);

// FastLED.addLeds<APA102, DATA_PIN, CLOCK_PIN, RGB>(leds, NUM_LEDS);
// FastLED.addLeds<DOTSTAR, DATA_PIN, CLOCK_PIN, RGB>(leds, NUM_LEDS);
}
// This function runs over and over, and is where you do the magic to light
// your leds.
void loop() {
// Move a single white led
for(int whiteLed = 0; whiteLed < NUM_LEDS; whiteLed = whiteLed + 1) {
// Turn our current led on to white, then show the leds
leds[whiteLed] = CRGB::White;
// Show the leds (only one of which is set to white, from above)
FastLED.show();
// Wait a little bit
delay(100);
// Turn our current led back to black for the next loop around
leds[whiteLed] = CRGB::Black;
}
}
Pouvez vous me dire si cela est faisable ??
Merci d'avance bonne journée.
