I have a ready-made and well-designed project that includes:
1- two ds18b20 temperature sensors;
Ethernet shield V2;
Тhe box of electronic items got very big and very tall, so I bought one ATmega328P WiFi - ESP8266.
Тhe program, which was written for Ethernet Shield, cannot work via WiFi.
Please help me to add the code to make the program work again with the WiFi module.
I want to change only a small part of the program that is connected to the Ethernet shield so that ModBus commands can work again.
