Electronic, 3D printing and embedded programming
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.
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.
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 WeMos D1 mini 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 this chapter we are going to wake on radio the LoRa E32 and microcontroller and we show the shield created for this device.
When you use a microcontroller an important features is store data, for logging or setting, for a web server or to show image. The better solution is an SD card, because It’s simple, small and low power device.
Now we are going to look how to connect and use with standard SD library with Arduino and esp8266.
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.
Here is a tutorial on the E32 LoRa (Long Range) device’s very cheap and long-range (from 3Km to 8Km).
Now we are going to understand the various transmission type
Here is a tutorial on the E32 LoRa (Long Range) device’s very cheap and long-range (from 3Km to 8Km).
It’s time to understand the configuration.
