Thank you so much Srikant for the video.I want to implement exactly the same thing but on raspberry pi.Can you please help me?
Thank you Srikant for this tutorial! I needed a system for a keypad tester and this is just what I was looking for! I modified the code slightly so it would say KEYPAD TESTER on the first line and display the digit on the second line, in the middle of the display just below the name in line one. Works great!
