![]() You can also turn the LED on and off by clicking a dynamic checkbox in the UpdateInterval -> 0. Ik = you can use Mathematica‘s Dynamic functionality to create a virtual slider in the notebook that will waggle back and forth as you move the physical slider attached to the InterfaceKit. Once the InterfaceKit is attached, you can query it for basic information like device name, serial number and sensor and IO options. You can include a timeout value if you’d like. Next, create a new instance of the InterfaceKit object, open it and wait for attachment. ![]() File path under OSX is available with short-key cmd+i. In a Mathematica notebook, you are going to load the J/Link package, install Java, and put the phidget21.jar file on your class path by editing the AddToClassPath command in the snippet below. Another question, which is possibly more a Mac question than a Mathematica. When everything is working correctly, you can close the program and open Mathematica. If you double click on the entry, it will start a demonstration program that allows you to make sure you can toggle the LED and get values back from the slider. It should show up in the General tab of system preferences. Once you have the hardware configuration you like, plug the InterfaceKit into the USB. For my test, I used a PhidgetInterfaceKit 8/8/8 with an LED on Output 2 and a 60mm slider (potentiometer) attached to Sensor 0. Once you have run Phidgets.mpkg you can open System Preferences and there will be a pane for Phidgets. Start by installing the Mac OS X Phidgets driver on your system. For more details, read the Java getting started tutorial and Phidgets programming manual, then look at the sample code and javadocs on this page. For a real application you would include error handling, event driven routines, and so on. This is basically a ‘hello world’ demonstration. In this case we can take advantage of Mathematica’s J/Link Java interface to call the Phidgets API. It is also quite straightforward to interact with Phidgets. If not, then you need to double check your activation key in the Mathematica User Portal.In my previous post, I showed how to connect an Arduino microcontroller to Mathematica on Mac OS X using the SerialIO package. If the correct Activation Key was entered, a message of "Activation successful!" will appear. Currently, I am running it on the following platform: Mac Mini (Mid 2011) 2.5 GHz Intel Core i5 8 GB RAM macOS Sierra 10.12. Type in the Activation Key from your User Portal download page and click Activate. Yes, Mathematica 11 works fine on macOS Sierra 10.12.
