Send email with attachments Arduino library 20

Send emails with attachments (v2.x library): Arduino Ethernet – 1

Today for Arduino ethernet.
Here I’d like to explain the version 2 of the EMailSender library, a big evolution respect to version 1, with support for Arduino with w5100, w5200 and w5500 ethernet shield and enc28J60 clone devices, and support for esp32 and esp8266.
Now you can add attachments also, loaded from storage device like SD or SPIFFS.

How to interface Arduino, esp8266 or esp32 to RS-485

RS-485 work as a broadcast; when you send a message, all devices connected to the wire receive that, so peoples use It is better to implement a lot of protocol to send a message to a specified device or a broadcast address. This article uses regular communication from two devices in a very simple way.
