    5. \n
  5. Select Amazon Echo from the list
    6. \n
  6. \n

    Select your model (in my case it is an Echo Dot)

    \n\n
    7. \n
  7. Now follow the directions on the screen to pair your new device!

Setting Up a Routine

\n

Here we are going to set up two different routines: one that starts the morning off and one that ends the morning. The one to start it needs to read you what is going on that day (according to the calendar that we will add), turn on the living room smart light, and start playing some music. The ending routine should stop the music and turn the living room light off in preparation of us leaving the house.

\n
    \n
  1. \n

    Before we can start adding routines, we need to make sure that we have all of the devices and skills we need added to the app

    \n\n
    2. \n
  2. \n

    First, we’ll set up our Apple Music

    \n\n
    3. \n
  3. \n

    Second, we’ll set up Google Calendar

    \n\n
    4. \n
  4. \n

    Lastly, we’ll add in our smart light

    \n\n
    5. \n
\n

Now, we’re ready to set up our routines! We’ll start with our morning start route

\n
    \n
  1. From the Alexa app, click on the hamburger menu on the top left of the screen and select Routines
    2. \n
  2. Click the ➕ in the top right hand corner to add a new routine
    3. \n
  3. Add a routine name (I just selected Morning Start)
    4. \n
  4. \n

    Add a When this happens

    \n\n
    5. \n
  5. \n

    Now it is time for the meat of the routine: the actions. First we will add an action to set the volume Alexa should speak at in the mornings

    \n\n
    6. \n
  6. \n

    Next, we want Alexa respond to our good morning

    \n\n
    7. \n
  7. \n

    Next, we want Alexa to turn on our smart light

    \n\n
    8. \n
  8. \n

    Next, we want Alexa to read us the calendar

    \n\n
    9. \n
  9. \n

    Finally, we need to set up Alexa to play Apple Muxic

    \n\n
    10. \n
\n

Now, we will set up the Morning end routine that will run when we leave the house in the morning

\n
    \n
  1. From the Alexa app, click on the hamburger menu on the top left of the screen and select Routines
    2. \n
  2. Click the ➕ in the top right hand corner to add a new routine
    3. \n
  3. Add a routine name (I just selected Morning End)
    4. \n
  4. \n

    Add When this happens

    \n\n
    5. \n
  5. \n

    Now time for the actions! First we will add and action to have Alexa respond

    \n\n
    6. \n
  6. \n

    Next, we want Alexa to turn the music off

    \n\n
    7. \n
  7. \n

    Finally, we want Alexa to turn off the light

    \n\n
    8. \n
  8. Your Alexa and routines are all set up! Give it a test by saying “Alexa, Good Morning” and then, “Alexa, goodbye”
    9. \n

Setting up The Weather Caja™

\n

The Weather Caja™ is a box that will help me know what I need to do in the mornings. It will read out the forecast for the day and let me know what the current temperature, low temperatures, and high temperatures for the day are. It will do this using and OLED screen and 3 LEDs all run by an ESP8266 microcontroller.

\n
    \n
  1. \n

    Wire up your OLED screen to your ESP8266 using the following diagram\n\n \n \n \n \n

    \n\n
    2. \n
  2. Wire up your 3 LEDs to D5, D6, D7 pins
    3. \n
  3. Use the code from previous labs to connect the ESP8266 to the internet, specifically WiFi
    4. \n
  4. \n

    Initialize the display using the following code

    \n
    #include <SPI.h>\n#include <Wire.h>\n#include <Adafruit_GFX.h>\n#include <Adafruit_SSD1306.h>\n#define SCREEN_WIDTH 128\n#define SCREEN_HEIGHT 64\n#define OLED_RESET     -1\nAdafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);
    \n
    5. \n
  5. \n

    After you have initialized the display begin communication in the setup() function with the following code

    \n
    if (!display.begin(SSD1306_SWITCHCAPVCC, 0x3C)) {\n  Serial.println("[OLED]\\tSSD1306 allocation failed");\n  for(;;);\n}
    \n
    6. \n
  6. \n

    Now you can write to the display using the following code

    \n
    display.clearDisplay();\ndisplay.setTextSize(1);\ndisplay.setTextColor(WHITE);\ndisplay.setCursor(0,0);\n// Display static text\ndisplay.println("[Your Text]");\ndisplay.display();
    \n
    7. \n
  7. Now you can write to the screen.
    8. \n
  8. Next, you should use the http client from ESP8266 to get the weather from any API you would like
    9. \n
  9. Use the ArduinoJson library to parse the JSON payload.
    10. \n
  10. Based on these values from the API, you are able to turn on and off certain lights if the clothes you need to wear need to be lit up
    11. \n
  11. Now, you have everything set up for your very own Weather Caja™. You just need to put it all in a box and make it look nice!!
    12. \n
