DynamoDB JavaScript SDK v2 v3: manage tables – 2
I want to write a step by step tutorial on how to create an Alexa Smart Home Skill from scratch.
We will learn how to manage tables with the JavaScript SDK v2 and v3.
DynamoDB: prerequisite and JavaScript SDK v2 and v3 – 1
I want to write a step by step tutorial on how to create an Alexa Smart Home Skill from scratch. So I’m going to present all the prerequisites and steps to create a Smart Home Skill connected to our micro-controller able to manage every connected device.
We will give a brief introduction to DynamoDB and the prerequisites required to work with the JavaScript SDK v2 and v3.
Send emails with attachments: Arduino SAMD boards (WiFiNINA) – 3
I would like to introduce version 2 of the EMailSender library, a great evolution compared to version 1, with support for Arduino with w5100, w5200 and w5500 ethernet devices and enc28J60 clone devices, support for esp32 and esp8266 and finally (from version 2.2.0) support for all Arduino (SAMD) devices using the WiFiNINA library (Arduino UNO WiFi Rev.2, Arduino NANO 33 IoT, Arduino MKR 1010 and Arduino MKR VIDOR 4000 WiFi etc.). Now you can add attachments also, loaded from storage device like SD or SPIFFS.
ABB (Power One) Aurora Web Inverter Monitor (WIM): WIFI configuration and REST Server – 6
I’d like to monitoring my ABB Aurora inverter. So with an WeMos D1 mini I create a centraline with web interface, notification and other.
Here I’d like to explain how to configure WiFi first time and I show REST API of the device.
WebSocket on Arduino, esp8266 and esp32: temperature and humidity realtime update – 3
Modern web application need realtime update, for year we use polling system with REST call but now we can’t ignore WebSocket.
Here a complete reference implementation of a web application with token authentication.
WebSocket on Arduino, esp8266 and esp32: server and authentication – 2
Modern web application need realtime update, for year we use polling system with REST call but now we can’t ignore WebSocket.
Here a WebSocket server with esp8266, esp32 with some method to enable authentication.
WebSocket on Arduino, esp8266 and esp32: client – 1
Modern web applications need to update data in real time, for years we have used polling with REST calls but now we can no longer ignore the WebSocket protocol.
Here I am going to present a WebSocket client with esp8266, esp32 and Arduino Mega with enc28j60.Here a WebSocket client with esp8266, esp32 and Arduino Mega and enc28j60.
Web Server with esp8266 and esp32: DHT temperature humidity on protected Web Interface – 6
Here a little tutorial to learn how to manage a complete web server via esp8266 esp32 or other arduino like device.
Now a simple project to put all the information you have learned a temperature humidity secure web interface that retrieve data from a DHT12.
Web server on esp8266: add secure REST back-end – 5
Here a little tutorial to learn how to manage a complete web server via esp8266 esp32 or other arduino like device.
To retrieve data we are going to add a REST end point protected by authentication.
