I'm newbie in Arduino programming so I hope to get a clear answer.
I have NodeMCU v1 12-E, I connected it with RFID RC522 as in attachment picture.
Now my question:
I need to connect I2C interface LCD module with it to print some words in.
The RFID use the default SDA and SCL pins on NodeMCU V1.0 "D1 and D2" also when I see wiring for the LCD I2C it use same D1 and D2 pins.
So now if I change the RFID instance creation code to
MFRC522 mfrc522(0,2); //SS_PIN 3 RST_PIN 4
Is the RFID will work as previous pins and the LCD will work also?
