35+ Arduino Pinout I2C
Background. I hope you found it useful and informative. If you are not using an arduino uno, the sda and scl pins can be at a different location.

Here one arduino will act as master and another one will act as slave. If you did, please share it. You can watch the following video or read the written tutorial below.
On the arduino uno they are found on analog pins a4 and a5.
Maybe it is because many of the pinout diagrams for the nano have scl and sda on the wrong pins. Hello there is a lack of clarity on the documentation page for arduino nano regarding pins designated for i2c comms. Maybe it is because many of the pinout diagrams for the nano have scl and sda on the wrong pins. I2c is an interesting protocol.
