byte rowPins[ROWS] = 2, 3, 4, 5; // Connect to keypad rows byte colPins[COLS] = 6, 7, 8, 9; // Connect to keypad columns
First, let's get the basics covered. In this context, a "library" is a pre-built, pre-tested model of an electronic component. Using one saves you from having to build a component from scratch and ensures it will simulate accurately and behave just like the real hardware.

If you are building a circuit from scratch, follow these three general steps:
const byte ROWS = 4; const byte COLS = 4; byte rowPins[ROWS] = 2, 3, 4, 5; //
Compile your code to generate the .HEX file, which you will upload to the Proteus microcontroller component. Step-by-Step Circuit Design in Proteus
Using a keypad library in Proteus can save you a lot of time and effort when designing and testing your projects. With a keypad library, you can easily simulate keypad inputs and test your project's response to different button presses. This can help you identify and fix errors early on, reducing the risk of costly rework or redesigns. return '0'; // Return a default value if
