Circuit Playground Express: Arduino-hid

In this case, we only need to change some code in Arduino IDE.

Now. we will use the X and Y values from the motion sensor on CPX to control the position of the nouse.

and left button on CPX to work as mouse left click.

Arduino HID:

 1#include "Mouse.h"
 2#include <Adafruit_CircuitPlayground.h>
 3float X, Y, Z;
 4//int leftButton;
 5bool mouseIsActive = false; 
 6int slideSwitch;
 7
 8void setup() {
 9  // put your setup code here, to run once:
10  CircuitPlayground.begin();
11  Mouse.begin();
12}
13
14void loop() {
15  //read slide switch from cpx.
16  slideSwitch = CircuitPlayground.slideSwitch();
17  // if the switch is on the CPX mouse is active, 
18  if(slideSwitch ==HIGH){
19    mouseIsActive=true;
20    }else{
21      //if the slide switch is off, the cpx mouse will be off
22      mouseIsActive=false;
23      }
24
25  //read the leftButton from cpx
26  int leftButton = CircuitPlayground.leftButton();
27  //x and y position from motion sensor
28  X = CircuitPlayground.motionX();
29  Y = CircuitPlayground.motionY();
30
31  //int xReading=map(x,-1,1,0,100);
32   // if the mouse control state is active, move the mouse with motion sensor X and Y value.
33  if (mouseIsActive) {
34    Mouse.move(X*2, Y*2, 0);
35  }
36
37 // if the mouse is not pressed, press it:
38  if (leftButton==HIGH){
39    if (!Mouse.isPressed(MOUSE_LEFT)) {
40      Mouse.press(MOUSE_LEFT);
41     }
42    }else{  // else the mouse button is not pressed:
43      if (Mouse.isPressed(MOUSE_LEFT)) {
44      Mouse.release(MOUSE_LEFT);
45    }
46      }
47  delay(5);
48}
