This project design to mine Duino-Coin using an Esp8266/Esp32 as a master and Arduino as a slave.
Using the I2C communication to connect all the boards and make a scalable communication between the master and the slaves.
DuinoCoinI2C Version 2.6
Arduino - Slave
All Slaves have the same code and should select the I2C Address automatically.
- DuinoCoin (Handle the
- ArduinoUniqueID (Handle the chip ID)
- StreamJoin (StreamString for AVR)
Automatic I2C Address
The I2C Address on the Arduino is automatically updated when the board starts, if an Address already exists on the I2C bus the code finds another Address to use.
Esp8266/Esp32 - Master
The master requests the job on the
DuinoCoin server and sends the work to the slave (Arduino).
After the job is done, the slave sends back the response to the master (Esp8266/Esp32) and then sends back to the
- ArduinoJson (Request Pool Version 2.6)
- ESPAsyncWebServer (ESPAsyncWebServer)
The code supports 10 clients and can be changed on the define:
#define CLIENTS 10
Connect the pins of the Esp8266 or Esp32 on the Arduino like the table/images below, use a Logic Level Converter to connect between the ESP and Arduino.
