We made buttons and mouse click in the class

/*

  Keyboard Message test

  For the Arduino Leonardo and Micro.

  Sends a text string when a button is pressed.

  The circuit:
  - pushbutton attached from pin 4 to +5V
  - 10 kilohm resistor attached from pin 4 to ground

#include "Keyboard.h"
#include <Mouse.h>

const int buttonPin = 2;         // input pin for pushbutton
int previousButtonState = HIGH;  // for checking the state of a pushButton
int counter = 0;                 // button push counter

void setup() {
  // make the pushButton pin an input:
  pinMode(buttonPin, INPUT);
  // initialize control over the keyboard:
  Keyboard.begin();
}

void loop() {
  // read the pushbutton:
  int buttonState = digitalRead(buttonPin);
  // if the button state has changed,
  if ((buttonState != previousButtonState)
      // and it's currently pressed:
      && (buttonState == HIGH)) {
    // increment the button counter
    counter++;
    // type out a message
    Mouse.click();
    Keyboard.releaseAll();
  }
  // save the current button state for comparison next time:
  previousButtonState = buttonState;
}

Also we iterated for our final project. Found our servo actuators and 3v3 ultrasonic sensors and plugged them all together.
