The coffee maker is designed to begin brewing as soon as you close the reservoir lid. To detect brewing, we put a light sensor on the bottom of the lid so we can see when brewing begins, and the Raspberry Pi the sensor is connected to posts to our database on AWS.
In the same script on the Raspberry Pi that posts to the database, I added a POST to a custom Slack integration.
Now whenever we make coffee or popcorn everyone gets the memo!

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
