I want to know how to connect an lcd i2c, with an led 8x8 matrix at the same time. The problem is, all the analog in pins are used, except A0 and A1. Using this tutorial:
https://www.makerguides.com/character-i2c-lcd-arduino-tutorial/
It says I must have analog pins A0-A2 with nothing connecting, except I have A2 connected, which is why both screens don't work right. So how can I use only pins A0-A1 with an lcd i2c? Thanks.
