Electronic, 3D printing and embedded programming
Microservices architecture is very popular for various reason, and It’s quite simple to implement with our microcontroller like esp32 or esp8266. POST, PUT, PATCH, DELETE.
Today for esp8266 and esp32.
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, SPIFFS or LittleFS per esp8266.
Serial Peripheral Interface Flash File System, or SPIFFS for short. It’s a light-weight file system for microcontrollers with an SPI flash chip. The on-board flash chip of the ESP32 has plenty of space for your files.
ESP32, a little guide on how to use this low cost but powerful microcontroller with WIFI integrated.
Pinout, specification and IDE configuration to start use your esp32.
Microservices architecture is very popular for various reason, and It’s quite simple to implement with our microcontroller like esp32 or esp8266. GET and JSON formatter.

Library to use i2c pcf8574 IC with arduino, esp8266 and esp32.
This IC can control (until 8) digital devices like button or led with 2 only pins.
Here I explain the manage of multiple rotary encoder.
When you create a datalogging It’s important to structure your data, sometime a good solution can be JSON format.
Here a tutorial on E32 LoRa (Long Range) device very cheap and very long range (from 3Km to 8Km).
In this chapter we are going to wake on radio the LoRa E32 and microcontroller and we show the shield created for this device.
Here a tutorial on E32 LoRa (Long Range) device very cheap and very long range (from 3Km to 8Km).
In the last chapter we are going to send complex structure.
