Node-RED and Android in IoT Application Development
summary
Node-RED is presented as a visual, node-based event engine that integrates with MQTT and HTTP to connect Arduino or Samsung Artik sensors to cloud logic. Examples show a noise-level monitor that parses HTTP, stores values, and sends email/SMS alerts; an LDR posting luminosity and triggering a tweet; an MQTT flow that toggles a lamp and updates a web/mobile dashboard; and workshops building web UIs and an Android MQTT client that publishes and subscribes to the same topics.
