艾鍗教你從實作中認識物聯網!
https://bit.ly/3kLZhAq
課程使用Raspberry Pi結合ARM mbed Cloud來實現一個物聯網解決方案。你會了解M2M(Machine-to-Machine)網路協定,包含CoAP、MQTT、LWM2M等協定,並藉由Raspberry Pi連接 Cloud。 Raspberry Pi的部份教你連接一些感測器,包含GPIO、數位界面I2C的溫溼度感測器、類比感測器如光感應器等,並將這些感測器成為定義為不同的Resource Path並註冊在mbed cloud中。
本課程將採用Node.js撰寫WebAPP,使用HTTP/RESTful API存取Resource。在實作WebAPP中,除了後端Node.js,你也將會看到後端如何與前端瀏覽器之間要如何溝通的方式,如AJAX或WebSocket
