Just a general note about I2C. I had a hard time finding information regarding pull up resistors for the SCL and SDA lines. In short, you should use pull up resistors. In this project I used 4.7k ohm resistors on the SCL and SDA lines, and they're connected to the master pro micro.

Note (from ): 4.7k is a starting point. If you have issues move down. It has to do with the line capacitance so if you start having error packets, try to reduce

I also have a public discord if you have any questions:
