If you have a graphical LCD, you will want to use openGLCD library. https://bitbucket.org/bperrybap/openglcd/wiki/Home

If you have a 1602 display, write the value you read to the display. There's a difference in writing and printing to the display.

Who's next to make an assumption and guess an answer based on that ?
