Measure the Freshness of your milk!
milk.js talks to the SPI bus on the Raspbery Pi and Gertboard extension board to read analog to digital signals measuring the weight of a gallon of milk. If the weight exceeds certain thresholds it will send either IOS Alert or Badge push notifications via AWS SNS.
To use AWS SNS pass your API credentials in config.json

"accessKeyId": "<access key>",
