Hello, can I use serial LCD without using Tx pin on arduino?
Can you be more specific about which 'serial LCD' you plan to use.
Most likely you are actually using or planning to use a serial adapter with a conventional parallel LCD module. Most of the currently popular serial adapters use I2C which does not use Tx or Rx.
This is my serial LCD spec:
- 5V powered 2 x 16 character
- SPI communication
SPI does not use the Tx or Rx pins.
Then what pin I should use. Sorry I am still beginner.

At the internet or arduino?
In order to get any real help here you're going to have to start showing a little initiative and do some searching. I'm feeling a tad generous today so I googled it for you.
Are they the same between arduino UNO and LEONARDO?
