Raspberry Pi Server for MuleSoft Hackathon

This server is implemented with Node.js, and Python.

Setup Instructions

First, make sure you have Node.js, and npm installed on your pi:

sudo apt-get update
sudo apt-get upgrade
sudo wget http://node-arm.herokuapp.com/node_latest_armhf.deb
sudo dpkg -i node_latest_armhf.deb
node -v    #check if node is installed successfully

Next, clone this repository and install all the dependencies:

npm install

Modify settings in pi.config if you need to, and start the server with the following command:

sudo node app

Note that the server needs to run as super user because it needs permissions to perform I/O operations on IO pins.

Sensors and APIs

Range Sensor

GET /rangeSensor

This method needs no parameters.

Toggle I/O Pin

GET /toggleIOPin

Calling this method will toggle a specific GPIO pin on the raspberry pi.

Parameters:

• pin : A number to specify the GPIO Pin you want to toggle on your Pi.
  • Eg. pin=3 toggles GPIO3 on/off.

Motion Sensor Hooks

POST /motionHook

Add a new web hook that triggers when the motion sensor detects a motion.

Parameters:

• address : A http address the pi will send a get request to when motion is detected.
  • Eg. address=http://127.0.0.1/callback

DELETE /motionHook

Remove a web hook for the motion sensor on the raspberry.

Parameters:

• address : A http address of the web hook you want to remove.
  • Eg. address=http://127.0.0.1/callback
