HTTPCoffeePot
Special Features
- 15 minute automatic shutoff
- Controlled via HTTP Requests
- Status, start, and stop requests
- Returns JSON for meant for AJAX interfaces
- Ready and Running LEDs.
HTTPCoffeePot can be connected to your arduino with an ethernet shield and attached to the network. It will listen on port 80, like a normal web server, and take several different request urls to control it. The urls return JSON with the intention that an ajax interface will be built over it:
- /status/ - This will return some information about the current status of the coffee pot
- /start/ - This will start the coffee pot assuming that it is currently ready to be started and not started already
- /stop/ - This will turn off the coffee pot
Currently the process will work like this:
- Put in coffee grounds/filter/water
- Press ready button to enter coffee pot into ready state
- When coffee is desired, send /start/ request
- Wait for coffee to finish
- Send manual /stop/ request OR wait for timed automatic shut off to take place after 15 minutes
I have a very simple coffee maker which is really only a switch. The modifications I made to the pot were to cut the power inside of it between the wall and the switch on the pot and place a relay in between. The relay is then activated by the Arduino board when sent the /start/ request.
You can find the circuit diagram for the relay hookup here
