Automating a Barn Using Arduino, Raspberry Pi, Micronaut, Streaming, Docker, Kubernetes, an Autonomous Database, and the Cloud
In this session learn about a project to automate tasks in a barn, including scheduling when the lights turn on and off, temperature monitoring, and a webcam. Explore the model and learn about the hardware and software used in it. At its core, the system uses an Arduino, Raspberry Pi, and various pumps, solenoids, motors, and sensors to simulate the automation of specific tasks such as filling a water bowl, opening, and closing doors, monitoring the environment and turning on and off lights on demand or via a schedule.
The hardware runs a client that has been implemented in several languages for demo purposes (currently Node and Groovy). The client interfaces with a messaging queue via a cloud-based microservice (also implemented in Node and Groovy with Micronaut) for messaging to both store sensor data in an autonomous database instance and stream data to the Angular front end in real time via server-sent events. The Raspberry Pi client also receives commands for remotely performing specific tasks on demand. The persisted data is formatted and displayed on a web application running in a Docker container that is deployed to a cloud-based Kubernetes cluster.
Look at both the hardware and software that power this system and see how the project can be used as a playground for learning new technologies, languages, and frameworks.
He’s obsessed with technology and programming and feels extremely lucky to get paid to do what he loves every single day. When not learning a new language, tool, or framework he can usually be found volunteering at his local school working with the FLL Lego Robotics club, working on his barn automation project built with Raspberry Pi and various sensors with a web-based interface, or making new friends at a conference.
