  Neopixel Strip - Setup and Testing

  Following this tutorial on Adafruit, test that the circuit for the led strip is working. 

  This is my modified code for this circuit so far:

  // Simple NeoPixel test.  Lights just a few pixels at a time so a
  // 1m strip can safely be powered from Arduino 5V pin.  Arduino
  // may nonetheless hiccup when LEDs are first connected and not
  // accept code.  So upload code first, unplug USB, connect pixels
  // to GND FIRST, then +5V and digital pin 6, then re-plug USB.
  // A working strip will show a few pixels moving down the line,
  // cycling between red, green and blue.  If you get no response,
  // might be connected to wrong end of strip (the end wires, if
  // any, are no indication -- look instead for the data direction
  // arrows printed on the strip).
  
  #include 
  
  #define PIN      6
  #define N_LEDS 136
  
  Adafruit_NeoPixel strip = Adafruit_NeoPixel(N_LEDS, PIN, NEO_GRB + NEO_KHZ800);
  
  void setup() {
    strip.begin();
  }
  
  void loop() {
    chase(strip.Color(255, 0, 0)); // Red
    chase(strip.Color(0, 255, 0)); // Green
    chase(strip.Color(0, 0, 255)); // Blue
  }
  
  static void chase(uint32_t c) {
    for(uint16_t i=0; i4; i++) {
        strip.setPixelColor(i  , c); // Draw new pixel
        strip.setPixelColor(i-4, 0); // Erase pixel a few steps back
        strip.show();
        delay(25);
    }
  }

  Here is a video of what the LEDs should look like when plugged into power, after you upload the code to the Arduino Mega:

  Capacitive Touch Sensor Modules - Setup and Testing

  Code for testing the capacitive touch sensor module below:

  #define touchPin 2
    
  int ledPin = 13;
   
  void setup() {
    Serial.begin(9600);
    pinMode(ledPin, OUTPUT);
    pinMode(touchPin, INPUT);
  }
   
  void loop() {
    int touchValue = digitalRead(touchPin);
    if (touchValue == HIGH) {
      Serial.println("TOUCHED");
      digitalWrite(ledPin, HIGH);
    } else {
      digitalWrite(ledPin, LOW);
    }
    delay(350);
  }

  Music Maker MP3 Shield - Setup and Testing

  Code below modified from player_simple example under the VS1053 library examples. Instructions on how to find this are here:

  https://learn.adafruit.com/adafruit-music-maker-shield-vs1053-mp3-wav-wave-ogg-vorbis-player/installing-software

  Note: Your music player files that are stored on your SD card must follow a 8.3 format. That is: up to 8 characters max, followed by a dot, followed by a 3 letter extension. For example: "track001.mp3".

  There is some extra soldering you have to do, to play music on the music maker mp3 shield by Adafruit on the Arduino Mega 2560. Basically you want to solder across the ICSP jumpers on the shield. See link below for more info and instructions:

  In the files section of this project, you can find all 96 greek word recordings (12 recordings for each of the 8 categories).
