Write code (Swift)

NOTE: the code below assumes you've created a single button and linked it to an IBAction named moveRover

  
import Cocoa
//Add Phidgets Library
import Phidget22Swift

class ViewController: NSViewController {

    //Create
    let leftMotors = DCMotor()
    let rightMotors = DCMotor()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        do{
            //Connect to wireless rover
            try Net.addServer(serverName: "", address: "192.168.100.1", port: 5661, flags: 0)
            
            //Address
            try leftMotors.setChannel(0)
            try rightMotors.setChannel(1)
            
            //Open
            try leftMotors.open()
            try rightMotors.open()
            
        }catch{
            print(error)
        }
        
    }

    @IBAction func moveRover(_ sender: Any) {
        do{
            //Turn in one direction
            try leftMotors.setTargetVelocity(1.0)
            try rightMotors.setTargetVelocity(-1.0)
            
            //Wait for 2 seconds
            sleep(2)
            
            //Stop motors
            try leftMotors.setTargetVelocity(0.0)
            try rightMotors.setTargetVelocity(0.0)
            
        }catch{
            print(error)
        }
    }
}
  

Practice

  1. Try turning your rover in the opposite direction.
  2. Try moving forwards, turning 180°, and moving back to your starting position.
Troubleshoot
  1. Make sure everything is plugged in properly and your VINT Hub is connected to your computer.
  2. Stop running other programs that are using your Phidgets before running a program.

What are Phidgets?

Phidgets are programmable, modular USB devices, either sensors or controllers that you can connect together. Simply write code in your favorite language and solve real-world problems.
