I got some Arduino Nanos at really good price on amazon and wanted to connect a 7 segment LED display with an I2C backpack.
I had some confusion initially but later found out that SDA and SCL on Arduino Nano are available on A4 and A5 pins.
- SDA -> A4
- SCL -> A5
In order to make them work , be sure to include the wire.h library.
Here are all the pins for the Arduino Nano.
In the mean time enjoy the short video.
