I want to move the mouse pointer with an Arduino and ultrasonic sensor

Question

I want to move the mouse pointer with an Arduino and ultrasonic sensor but when I compiled it says

Mouse.h not found

and I don't know what I can do.

Here is my code;

 #include <Mouse.h>
int echoPinCursor=2;
int trigPinCursor=3;
int echoPinBtn=4;
int trigPinBtn=5;
int echoPinScroll=6;
int trigPinScroll=7;
int x;
int y;
long duracionCursor, distanciaCursor;
void setup() {
 Serial.begin(9600);
 pinMode(trigPinCursor, OUTPUT);
 pinMode(echoPinCursor, INPUT);
 pinMode(trigPinBtn, OUTPUT);
 pinMode(echoPinBtn, INPUT);
 pinMode(trigPinScroll, OUTPUT);
 pinMode(echoPinScroll, INPUT);
}
void loop() {
 //mover el cursor
 int direccionx=moverx();
 int direcciony=movery();
 Mouse.move(direccionx, direcciony,0);
 delay(2);
}
int moverx(){
 distanciaCursor=obtener_distanciaCursor();
 if (distanciaCursor >= 1 || distanciaCursor <= 11){
 x--;
 }
 if (distanciaCursor >= 12 || distanciaCursor <= 24){
 x++;
 }
 return x;
}
int movery(){
 distanciaCursor=obtener_distanciaCursor();
 if (distanciaCursor >= 25 || distanciaCursor <= 37){
 y--;
 }
 if (distanciaCursor >= 38 || distanciaCursor <= 50){
 y++;
 }
 return y;
}
long obtener_distanciaCursor(void)
{
 digitalWrite(trigPinCursor, LOW);
 delayMicroseconds(2);
 digitalWrite(trigPinCursor, HIGH);
 delayMicroseconds(10);
 digitalWrite(trigPinCursor, LOW);
 duracionCursor = pulseIn(echoPinCursor, HIGH);
 distanciaCursor = duracionCursor/58.2;
return(distanciaCursor);
}

That's because the Uno can't be a mouse. For that you need the Leonardo or something else with a similar "U" style microcontroller.

If you are adventurous, and you have a genuine Arduino, you can reprogram the USB controller chip with new firmware so it thinks it's a mouse, but programming the main MCU is then a real chore.
