I have 2 Serials in Arduino
Serial = To print data string in serial (dataRaspi)
Serial1 = To read the datas from 'Serial1' and print this out on LCD Screen.
Parallel To Serial Shift Register
Here is my Code
The Question is...
my lcd got blank if i give a series of string input to serial1 like 'qwerty'. How to display the result from serial1 to my lcd display?
