Kotlin & Implications in an IoT project

on YouTube ↗40m

" summary

Prototype uses Kotlin + Android Things on a Raspberry Pi (and mentions NXP Pico) to read GPIO buttons, toggle an LED via PeripheralManager and callbacks, and close pins on shutdown. Device talks to backend over MQTT with Mosquitto or HTTP, uses certificate-based credentials for auth, and targets serverless functions for cost-efficient ingestion. Covers protocol choices (Bluetooth, ZigBee, LoRa, cellular), connectivity cost examples (~$2/month SIMs) and tradeoffs between microcontrollers and microprocessors.
