How do I code a program to move my mouse in X, Y

You can do this using an arduino acting as a mouse.

The mouse functions enable 32u4 or SAMD micro based boards to control cursor movement on a connected computer through their micro’s native USB port. When updating the cursor position, it is always relative to the cursor’s previous location.

The mouse can be moved using the Mouse.move() function. Keep in mind that you must first call Mouse.begin()

Here is an example of this function in action.

#include <Mouse.h>

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 maxima[] = {
  0,0};                       // actual analogRead maxima for {x, y}
int axis[] = {
  xAxis, yAxis};              // pin numbers for {x, y}
int mouseReading[2];          // final mouse readings for {x, y}

void setup() {

void loop() {

// read and scale the two axes:
  int xReading = readAxis(0);
  int yReading = readAxis(1);

// move the mouse:
    Mouse.move(xReading, yReading, 0);

  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;
