In this workshop, learn how to develop a multi-tenant platform for a connected drink dispenser. Work with firmware on microcontrollers using Amazon FreeRTOS, deploy your own application and user management framework with static Amazon S3 websites and Amazon Cognito, and utilize AWS IoT Core for immediate telemetry, command, and control of your drink dispenser devices. When ready, plug your controller into one of the physical dispensers to complete the workshop.
