Habe mal wieder ein Problem.
Ich möchte durch einen IR Sensor TCRT 5000 einen LED Stripe ( 60 LED´s) WS 2812 ansteuern.
Ich möchte wie beim letzten Post ( nochmals Danke an alle ), das wenn ein RC->Car den IR-Sensor auslöst, das die LED Stripe´s für 10 Sekunden ausgelöst werden.
Ich habe den Standard Sketch genommen und würde den wenn möglich erweiter.
Weiß aber wieder nicht wie
// NeoPixel Ring simple sketch (c) 2013 Shae Erisson
// Released under the GPLv3 license to match the rest of the
// Adafruit NeoPixel library
#include <Adafruit_NeoPixel.h>
#ifdef __AVR__
#include <avr/power.h> // Required for 16 MHz Adafruit Trinket
#endif
// Which pin on the Arduino is connected to the NeoPixels?
#define PIN 6 // On Trinket or Gemma, suggest changing this to 1
// How many NeoPixels are attached to the Arduino?
#define NUMPIXELS 60 // Popular NeoPixel ring size
// When setting up the NeoPixel library, we tell it how many pixels,

Adafruit_NeoPixel pixels(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);
#define DELAYVAL 10 // Time (in milliseconds) to pause between pixels
void setup() {
// These lines are specifically to support the Adafruit Trinket 5V 16 MHz.
// Any other board, you can remove this part (but no harm leaving it):
#if defined(__AVR_ATtiny85__) && (F_CPU == 16000000)
clock_prescale_set(clock_div_1);
#endif
// END of Trinket-specific code.
pixels.begin(); // INITIALIZE NeoPixel strip object (REQUIRED)
}
void loop() {
pixels.clear(); // Set all pixel colors to 'off'
// The first NeoPixel in a strand is #0, second is 1, all the way up
// to the count of pixels minus one.
for(int i=0; i<NUMPIXELS; i++) { // For each pixel...
// pixels.Color() takes RGB values, from 0,0,0 up to 255,255,255
// Here we're using a moderately bright green color:
pixels.setPixelColor(i, pixels.Color(255, 0, 0));
pixels.show(); // Send the updated pixel colors to the hardware.
delay(DELAYVAL); // Pause before next pass through loop
}
}
Den IR Sensor habe ich wie folgt angeschlossen.
VCC und GRN ist ja klar.
DO habe ich auf dem Arduino R3 Board an Digital PWM 2 angeschlossen.
Ich hatte folgendes ausprobiert was aber nicht funktioniert hat.

IRrecv irrecv(IR_PIN);

}
}
}
Bekomme folgende Fehlermeldungen :-(

Wer könnte mir hierbei behilflich sein ??
