Simulation of the circuit in Proteus version 8.8

[Jmur30]

Excuse me friend could you help me, I am not so good at programming, simulate the scheme with the code you uploaded in the proteus program version 8.8, and I wanted to know in which program you did the coding, since I want to remove the "0" others that They show on the LCD screen (16x2) and the response time when pressing each button. Thank you
