When you push the button, alerts that we are making coffee to Slack. Ten minutes later, it says the coffee is done.
Installation / setup: follow [particle-cli instructions][particle-instructions]
particle-instructions: http://docs.particle.io/core/connect/#connecting-your-device-connect-over-usb
Also, you need to copy env_vars.example.h and change the constants to be where
the coffee server is located (see HTTP client information below).
You can compile the firmware with:
particle compile .Assuming your spark core is named spark-coffee, upload the compiled firmware
with:
particle flash spark-coffee <firmware path>I'd like to make a script to automate compiling and flashing.
To see the serial monitor in your terminal (useful for debugging):
particle serial monitor # lists some serial connections, can call by name
particle serial monitor 1 # connect to the first serial connectionI'm not doing posts in JSON because the Slack endpoint is over HTTPS and the HttpClient library doesn't handle HTTPS requests at this point. Instead, we hit an intermediate server where all of the posting logic lives.
To prevent random people from posting to our Slack channel and fooling us that coffee is ready and thereby greatly disappointing us, we never put the locations of our Slack endpoint or the intermediate server in source control (especially since this will likely be open-sourced.)
