Weather you have a sophisticated, dedicated bar in your home or you're merely a college student with bottles of Captain in your fridge, you Will run out of whiskey at some point. You might even have that same problem multiple times before you restock you supply or be forced to settle for vodka. Don't be that guy. You have the golden opportunity to receive automatic notifications to remind you that you have ran out of whiskey. As a bonus, it acts as a reminder to put your bottle back in the fridge if you happen to have just left it sitting out. Don't drink warm liquor. Get this set up.
Our project uses two particle photons and two photoresistors to let you know when you are out of whiskey. The first set notices when the fridge is open with a reading from the photoresistor and sends the signal to the second photon to check for the whiskey. The second one will determine if the whiskey is there or not and flashes an LED based on how much light is returned to the second photoresistor. If the photoresistor registers a value below calibrated threshold, the whiskey is not there then it will notify the IFTTT app on your phone with a notification to reminder you to return the whiskey. For every value recorded, IFTTT also sends an entry to google drive to add the data to a spreadsheet. It can be useful to have a record kept of when the whiskey was last taken from the fridge.
