Does your project need a high degree of control from your users? The Thumbstick Phidget provides a familiar 2-axis thumbstick similar to those on a video game controller. The stick springs back to the neutral position when released. It can also be pressed down with a click, which will register in software and can be tied to a function in your software. The HIN1100 connects to a port on a VINT Hub. See the Comaptible Products tab for a list of hubs.
The two axes of the thumbstick correspond to two VoltageRatioInput software objects which each range from -1.0 to 1.0, with zero being in the neutral position. These two numbers can be combined and converted into an angle and a magnitude in your software to be more useful. When the stick is pressed down, a DigitalInput object will change from false to true, so your program can use the change event to trigger a function or feature of your project.

Next, you will need to connect the pieces:
Now that you have everything together, let's start using the HIN1100!.
In order to demonstrate the functionality of the HIN1100, the Phidget Control Panel running on a Windows machine will be used.
The Phidget Control Panel is available for use on both macOS and Windows machines. If you would like to follow along, first take a look at the getting started guide for your operating system:
Linux users can follow the getting started with Linux guide and continue reading here for more information about the HIN1100.
After plugging the HIN1100 into your computer and opening the Phidget Control Panel, you will see something like this:
The Phidget Control Panel will list all connected Phidgets and associated objects, as well as the following information:
The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.
Double-click on a Digital Input object in order to run the example:
General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:
When you double click on an Joystick Axis object, a window like the one pictured will open.
For many applications like remote controlled vehicles, you'll want to convert the 2-axis data of the Thumbstick Phidget into an angle and magnitude. You can use the following formulas:
Where r is the magnitude, ϕ is the angle, and x and y are the two axis values. Atan2 is the 2-argument arctangent function, which you can find in most math libraries. For example, in C# you could use
Since x and y range from -1.0 to 1.0, the resulting r will range from to , so you may also want to modify the first formula like so:
This way, your r will range from 0 to 1, which is better when using the Thumbstick Phidget as a controller.
The current consumption of the HIN1100 depends on the data interval being used:
This Phidget is a smart device that must be controlled by a VINT Hub. For more information about VINT, have a look at the VINT Primer. You can use a Phidget Cable to simply and easily connect the two devices. Here's a list of all of the different VINT Hubs currently available:
Use a Phidget cable to connect this device to the hub. You can solder multiple cables together in order to make even longer Phidget cables, but you should be aware of the effects of having long wires in your system.
