Get a backpack for the LCD. This will probably have an i2c interface which connects to pins A4 & A5 on Uno.
AdaFruit make a backpack which also has an SPI interface. This could share several pins with the SD card. But it's also more expensive.
"if you just saw there, I asked what could I do with the existing sensors and board. I nowhere mentioned buying other things because using a MEGA board would probably solve my problem (ikt).
PaulRB:
Did you know that you can use the analog input pins as digital input or output pins?
It would be kind o f you to help me out with the declarations that I would have to make in the program to do that.

Well, take care with that. The forum moderators can sometimes come down hard on cross-posters. Robin2 is just trying to warn you.
Well you don't need to worry about that!
