KBlinkt! - Kotlin Native program to control a Blinkt! HAT

Why Kotlin Native?

Everybody uses Python or C to control their Pi HATs. Neither of both languages are my favourite. That's why I tried out Kotlin Native which means no JVM and just a single executable *.kexe file.

What's about Blinkt?

The Pimoroni Blinkt! Raspberry Pi HAT has everything a Tinkerer needs. It shines bright and has RGB colouring. Besides this, it is one of the more simpler HATs and a great way to get started.

Features

• Deployment to a Pi using a convenient shell script
• Control LEDs using Kotlin functions
• Add "plugin"-system for light modes
• Control LEDs using remote computer's curl commands
• Control LEDs using a simple web interface

Available web interface

After booting up the app, you can connect to http://pi:8080/ and control the Blinkt! HAT using your browser.

Available curl commands

# Turn off all the things
curl -X POST http://pi:8080/on
curl -X POST http://pi:8080/off

# Light mode sample
# See `turnLightMode` for more supported ids
curl -X POST http://pi:8080/lightmode -d "red"
curl -X POST http://pi:8080/lightmode -d "rainbow"
curl -X POST http://pi:8080/lightmode -d "cycle"

# Morse word
curl -X POST http://pi:8080/morse -d "hello"

# System shutdown
curl -X POST http://pi:8080/shutdown

Caution: I'm a Kotlin Beginner

If you put my motivation besides, I'm a Kotlin beginner. That means it may not be the best idea to just copy and paste my code, but maybe it could be the beginning of your Kotlin Native and Raspberry Pi journey. Please let me know!
