Im already using all analog in pins on uno r4, can i still use SDA and SCL pins in top right for i2c lcd, or are they just separate way to acces a4 and a5 pins, because ive seen conflicting information on this
Really? I find that odd. I've looked at the Uno R4 WiFi schematics many times and they always give me the same answer.
they are same pin
A4 = SCL
A5 = SDA
i don't think any beginner would be able to read the schematics you have attached.
when i was learning simple Mathematics, every time i solved the same problem/question , I got different answers.
When in doubt, you go to the source. Which in this case is the schematics for the board.
