Using The Pmod CLS With Arduino Uno

/************************************************************************
*
* Test of the Pmod module
*
*************************************************************************
* Description: Pmod_CLS
* message sent from serial monitor will be show on LCD display.
*
* Material
* 1. Arduino Uno
* 2. Pmod CLS (Jumpers on positions MOD0 and MOD2)
* See instructions list on https://reference.digilentinc.com/pmod/pmod/cls/user_guide
