Hi everyone,
I am trying to make my joystick mouse completely functioning (normal click, drag, etc.). As of now I am stuck with how to allow it to differentiate between a regular click and a drag click (I'm using variable called: var). Here's my program (it started as the example on the website):
/*
JoystickMouseControl
Controls the mouse from a joystick on an Arduino Leonardo or Micro.
Uses a pushbutton to turn on and off mouse control, and
a second pushbutton to click the left mouse button
Hardware:
- 2-axis joystick connected to pins A0 and A1
- pushbuttons connected to pin D2 and D3
The mouse movement is always relative. This sketch reads
two analog inputs that range from 0 to 1023 (or less on either end)
and translates them into ranges of -6 to 6.
The sketch assumes that the joystick resting values are around the
middle of the range, but that they vary within a threshold.
WARNING: When you use the Mouse.move() command, the Arduino takes
over your mouse! Make sure you have control before you use the command.
This sketch includes a pushbutton to toggle the mouse control state, so
you can turn on and off mouse control.

// set pin numbers for switch, joystick axes, and LED:
const int switchPin = 5; // switch to turn on and off mouse control
const int selPin = 4; // input pin for the mouse pushButton
const int xAxis = A0; // joystick X axis
const int yAxis = A1; // joystick Y axis
const int ledPin = 7; // Mouse control LED
// parameters for reading the joystick:
int range = 12; // output range of X or Y movement
int responseDelay = 5; // response delay of the mouse, in ms
int threshold = range/4; // resting threshold
int center = range/2; // resting position value
boolean mouseIsActive = false; // whether or not to control the mouse
int lastSwitchState = LOW; // previous switch state
int var = 1;
int varstate = digitalRead(selPin);
void setup() {
pinMode(switchPin, INPUT); // the switch pin
pinMode(ledPin, OUTPUT); // the LED pin
pinMode(selPin, INPUT);
// take control of the mouse:
digitalWrite(selPin, HIGH);
Mouse.begin();
Serial.begin(9600);
}
void loop() {
// read the switch:
int switchState = digitalRead(switchPin);
// if it's changed and it's high, toggle the mouse state:
if (switchState != lastSwitchState) {
if (switchState == HIGH) {
mouseIsActive = !mouseIsActive;
// turn on LED to indicate mouse state:
digitalWrite(ledPin, mouseIsActive);
}
}
// save switch state for next comparison:
lastSwitchState = switchState;
// read and scale the two axes:
int xReading = readAxis(A0);
int yReading = readAxis(A1);
// if the mouse control state is active, move the mouse:
if (mouseIsActive) {
Mouse.move(xReading, -yReading, 0);
}
int varstate = digitalRead(selPin);
for(int i = 1; varstate == LOW; i++) {
var++;
varstate = digitalRead(selPin);
if (varstate == HIGH && var > 1 && var < 150) {
Mouse.click(MOUSE_LEFT);
var = 1;
}
while(var > 150 && varstate == LOW) {
Mouse.press();
var++;
varstate = digitalRead(varstate);
}
Mouse.release();
var = 1;
}
Serial.println (var);
delay(10);
}
int readAxis(int thisAxis) {
// read the analog input:
int reading = analogRead(thisAxis);
// map the reading from the analog input range to the output range:
reading = map(reading, 0, 1023, 0, range);
// if the output reading is outside from the
// rest position threshold, use it:
int distance = reading - center;
if (abs(distance) < threshold) {
distance = 0;
}
// return the distance for this axis:
return distance;
}
Let me know if you have any ideas or answers.
Thanks in advance!
