Coffeebot 3000 - An IoT story with a RaspberryPI, Redis, LEDs, and Mario
by James Alexander, Leaf Solutions

This is a story about the creation, maintenance and on-going features built onto an IoT device to measure the amount of coffee in a coffee pot.

Topics and technology covered:

• Managing RaspberryPI Wifi connections
• Reading binary data from a USB scale
• Drawing Bitmap art to an LED Display connected via GPIO to the RaspberryPI
• Using Redis PubSub to control the queue of graphics and animations displayed on the LED panel.

Features of Coffeebot 3000:

• Measures the remaining coffee in a pot, and displays the amounts on an LED panel
• Responds when a user lifts the pot, and updates the display after replacing the pot
• If the pot has less than 1 mug, or has been on the scale for 2 hours or more, a random animation will be shown.Possible animations: Mario running across the display, a group of Red LEDs oscillating back and forth, or Conway's Game Of Life in various initial configurations with random colors for each pixel.

We will also have a special demonstration of CrowdPixie by Gene O'Donnell. Don't miss out on your chance to win some IndyPy Swag or a CrowdPixie t-shirt! Download the free CrowdPixie App for iPhone or Android.
