Moves the cursor on a connected computer. The motion onscreen is always relative to the cursor’s current location. Before using Mouse.move() you must call Mouse.begin()
Mouse.move(xVal, yVal, wheel);
xVal: amount to move along the x-axis - signed char
yVal: amount to move along the y-axis - signed char
wheel: amount to move scroll wheel - signed char

const int xAxis = A1; //analog sensor for X axis
const int yAxis = A2; // analog sensor for Y axis
int range = 12; // output range of X or Y movement
int responseDelay = 2; // response delay of the mouse, in ms
int threshold = range / 4; // resting threshold
int center = range / 2; // resting position value
int minima[] = {1023, 1023}; // actual analogRead minima for {x, y}

int axis[] = {xAxis, yAxis}; // pin numbers for {x, y}
int mouseReading[2]; // final mouse readings for {x, y}
void setup() {
Mouse.begin();
}
void loop() {
// read and scale the two axes:
int xReading = readAxis(0);
int yReading = readAxis(1);
// move the mouse:
Mouse.move(xReading, yReading, 0);
delay(responseDelay);
}
/*
reads an axis (0 or 1 for x or y) and scales the
analog input range to a range from 0 to <range>
*/
int readAxis(int axisNumber) {
int distance = 0; // distance from center of the output range
// read the analog input:
int reading = analogRead(axis[axisNumber]);
// of the current reading exceeds the max or min for this axis,
// reset the max or min:
if (reading < minima[axisNumber]) {
minima[axisNumber] = reading;
}
if (reading > maxima[axisNumber]) {
maxima[axisNumber] = reading;
}
// map the reading from the analog input range to the output range:
reading = map(reading, minima[axisNumber], maxima[axisNumber], 0, range);
// if the output reading is outside from the
// rest position threshold, use it:
if (abs(reading - center) > threshold) {
distance = (reading - center);
}
// the Y axis needs to be inverted in order to
// map the movemment correctly:
if (axisNumber == 1) {
distance = -distance;
}
// return the distance for this axis:
return distance;
}When you use the Mouse.move() command, the Arduino takes over your mouse! Make sure you have control before you use the command. A pushbutton to toggle the mouse control state is effective.
