Want to add an LCD display screen for the output motor
From this instructable:

// include the library code:
#include &lt;LiquidCrystal.h&gt;

// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup() {
  // set up the LCD's number of columns and rows:
  lcd.begin(16, 2);
  // Print a message to the LCD.
  lcd.print(" **Text for line 1 of LCD**");
  lcd.setCursor(0, 1);
  lcd.print(" **Text for line 2 of LCD**");
  // THE REST OF YOUR SETUP
}

void loop() {
    if (digitalRead(13) == HIGH) {
        // I assume this is the motor going forward
        lcd.print("motor 1 run forward");
    }
}
