Hi,
@fayyazmalik

run I2C_Scanner.ino on the arduino nano and see if it finds the I2C address.

ok no problem

Hi, @fayyazmalik
Welcome to the forum.

Can I suggest you desolder and resolder the joints to the header pins.
If you are using Unleaded Solder, forget it and use proper Leaded solder?

Have you used flux or resin cored solder?

Possibly not enough heat, or not applying the soldering iron for long enough to heat the complete joint before adding the solder.
