Javascript Interface

To initialize the Laser create a new PNTLaser object with 3 arguments:

1. Address of websocket server, 'ws://achex.ca:4010' is very recommended
2. ID of the controller. In future userful for security
3. ID of the Point'N'Turn Laser device. (Right now hard-coded on line 14 in websocket.ino file)
4. Optional ID of a log element

Initialize laser

var laser = new PNTLaser('ws://achex.ca:4010', 'PNTC', 'PNTL');

// moves the servos of laser pointer by X and Y degrees
// for example move(-3, 0) or move(3, -3)
laser.move(int x, int y);

// centers the laser
laser.center()

// moves the serovs of laser pointer to a random direction
laser.moveRandom()

// Turns laser ON
laser.laserOn()

// Turns laser OFF
laser.laserOff()

// Returns:
// false - no limit is hit
// '+' - limit hit on top
// '-' - limit hit on bottom
laser.limitX()

// Returns:
// false - no limit is hit
// '+' - limit hit on top
// '-' - limit hit on bottom
laser.limitX()

// Returns:
// true - connection is alright
// false - connection is lost or timed out (1000 ms)
laser.connected();

// returns last delay in ms
laser.getDelay();

// both Laser and Platform have switchLED() method which switches embedded LED on and off
platform.switchLED();

Initialize platform

var platform = new PNTPlatform('ws://achex.ca:4010', 'PNTC', 'PNTP');


// moves the platform by Step of size (1-3) which takes 300ms
// Positive goes right, negative goes left
platform.rotate(Step);

// both Laser and Platform have switchLED() method which switches embedded LED on and off
platform.switchLED();

// Returns:
// true - connection is alright
// false - connection is lost or timed out (1000 ms)
platform.connected();

// returns delay in milliseconds
platform.getDelay()

ToDo

1. Make the DEVICEID in the code as a variable
2. Interface for connecting to different wifis than 'SDU-GUEST' for ESP
