RPi-AppsScript-Christmas-Tree

Materials needed:

• Raspberry Pi with Python installed
• "GPIO" and "requests" modules for Python
• PowerSwitch Tail II (5V to 120V relay)
• 2 jumper wires

Setup

1. If you haven't already, install the "GPIO" module on your RPi:

from pi@raspberrypd ~ $

Test if you have it:

sudo python import RPi.GPIO as GPIO

If you don't see an error, you're all set. Otherwise install the module:

sudo apt-get update sudo apt-get install python-rpi.gpio

2. If you haven't already, install the "requests" module on your RPi

sudo apt=get install python-requests

3. Go to Google Drive and add "Apps Script" to your Drive applications under "Create -> Connect more apps"

4. Create a standalone Apps Script and paste in the code for christmasTreeWebService.gs
   Publish this script as a web service (Publish -> Deploy as web app) to run as you, and to be accessible to anonymous users. Copy the URL to your web app.

5. Create a text file for the Python code with a .py extension and put in the home directory on your Pi.
   Copy and paste the christmasTreeClient.py code into this file. IMPORTANT: Replace the with your own web app url.

6. Use jumpers to connect RPi pin 25 to the + in and the RPi ground pin to the - in contacts on the PowerSwitch tail. Plug in 120V Christmas tree lights.

7. Run the python script as the root user (necessary if you want the I/O pins) and test the web app.

8. If you want the python program to resume on boot, set up a Cron job to run the program upon bootup..
