Transcodex graphique

#include <Keypad.h> #include <Adafruit_NeoPixel.h>

Which pin on the Arduino is connected to the NeoPixels? On a Trinket or Gemma we suggest changing this to 1 #define PIN 13

How many NeoPixels are attached to the Arduino? #define NUMPIXELS 14 When we setup the NeoPixel library, we tell it how many pixels, and which pin to use to send signals. Note that for older NeoPixel strips you might need to change the third parameter–see the strandtest example for more information on possible values. Adafruit_NeoPixel pixels = Adafruit_NeoPixel(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);
