Pins pulled low when not called for

Hi,
I posted this https://forum.arduino.cc/index.php?topic=357478.0 in the software section but I think it maybe an electrical issue.

When running the code to show a text on the display, pins D2 and D3 are pulled low activating relays connected to them.

Anyone can shine a light to my issue? I’d really appreciated it.

TIA

Apparently, D2 & D3 are shorted to SDA & SCL respectively on the YUN and that’s why I’m having the problem.

So I just cannot use the two digital pins when SDA and SCL are in use.

If I’m mistaken, please let me know but I used an ohm meter to verify the continuity between the above pins.

Thank you. Issue closed.

No ohm meter necessary. It is clearly stated on the product page. Pins 2 and 3 are also the I2C pins.
