In this video we will program an AT89C51 to scan a 4x4 matrix key pad and display, which key is pressed on a 7 segment display.
The program that I am using to write code with is called Keil µVision 5. You can find and download it here: https://www.keil.com/download/product/​
As I an not the one who did the actual programming, So, I will provide you with the link of the individual who actually did the programming, if you need further instruction on the programming aspect.
