The Touch Wheel Phidget uses capacitive touch technology, similar to the touchscreen on a smartphone. Capacitive touch sensors such as this can detect a touch through a piece of glass or plastic of up to 3mm thick, so you can hide this board inside an enclosure or behind a panel. This Phidget connects to your computer through a VINT Hub.


  • Four capacitive touch regions - each region can be assigned a different function in your program
  • One scroll wheel pad
  • Adjustable sensitivity
  • Automatic recalibration if an object is present for over sixty seconds, preventing regions from being locked by unintentional objects like dirt or debris.


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:

Product Board
Image Part Number Price Number of VINT Ports Controlled By

HUB5000_0 $60.00 6 Local Network (Ethernet or Wi-Fi)
SBC3003_0 $120.00 6

Phidget Cables

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.

Part 1: Setup

Next, you will need to connect the pieces:

HIN1001 Functional.jpeg
  1. Connect the VINT Hub to your computer with a USB cable.
  2. Connect the HIN1001 to the VINT Hub using the Phidget cable.

Phidget Control Panel

In order to demonstrate the functionality of the HIN1001, 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.


To open the Phidget Control Panel on Windows, find the Ph.jpg icon in the taskbar. If it is not there, open up the start menu and search for Phidget Control Panel

Windows PhidgetTaskbar.PNG


To open the Phidget Control Panel on macOS, open Finder and navigate to the Phidget Control Panel in the Applications list. Double click on the Ph.jpg icon to bring up the Phidget Control Panel.

For more information, 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 HIN1001.

First Look

After plugging the HIN1001 into your computer and opening the Phidget Control Panel, you will see something like this:

HIN1001 Panel.jpg

The Phidget Control Panel will list all connected Phidgets and associated objects, as well as the following information:

  • Serial number: allows you to differentiate between similar Phidgets.
  • Channel: allows you to differentiate between similar objects on a Phidget.
  • Version number: corresponds to the firmware version your Phidget is running. If your Phidget is listed in red, your firmware is out of date. Update the firmware by double-clicking the entry.

The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.

Part 2: Using Your Phidget


The Touch Wheel Phidget provides one scroll wheel and seven capacitive touch regions with adjustable sensitivity.

Explore Your Phidget Channels Using The Control Panel

You can use your Control Panel to explore your Phidget's channels.

1. Open your Control Panel, and you will find the following channels:

HIN1001 Panel.jpg

2. Double click on a channel to open an example program. Each channel belongs to the CapacitiveTouch channel class:

Capacitive Scroll Sensor: Detects a touch or the close proximity of your hand or other conductive objects

In your Control Panel, double click on "Capacitive Scroll Sensor":


Part 3: Create your Program

Part 4: Advanced Topics and Troubleshooting

How do I know what channel, serial number, or hub port to use in my program?

Before you open a Phidget channel in your program, you can set these properties to specify which channel to open. You can find this information through the Control Panel.

1. Open the Control Panel and double-click on the red map pin icon:

The locate Phidget button is found in the device information box

2. The Addressing Information window will open. Here you will find all the information you need to address your Phidget in your program.

See the Phidget22 API for your language to determine exact syntax for each property.

Interaction with Data Interval

Unlike most other Phidgets, setting a data interval on the HIN1001 affects its initial “wake up” time, instead of the overall data rate. After the first touch has been detected, the device will stream data as fast as possible (up to every 16ms, as data becomes available).

This means that if setting a data interval of 250ms, the first touch may need to be held up to 250ms to wake the device, after which subsequent touches on all channels will be detected much faster, until no touch is detected for a few seconds. Once the device has been left alone for a few seconds, it will resume its low-power state and wait for the next touch.


The capacitive touch sensors rely on checking capacitance against a threshold to detect when they are touched. As a result you need to keep a good baseline of the capacitance of the sensor's environment. The HIN1001 will recalibrate its baseline levels if it detects a constant touch for more than 50 seconds, in order to prevent getting stuck in a touched state. Similarly, it will recalibrate its baseline capacitance to adjust to falling capacitance (such as when it is moved away from a surface) in order to prevent getting stuck in a not-touched state. The latter adjustment happens as soon as the baseline is detected to have fallen.

Relative Change in Position
CapacitiveTouch CircularPositionChange.jpg

Since the touch wheel is circular, calculating the change in position of a finger over the wheel can be more involved than simply subtracting one position from another. In cases where the value crosses the zero point, a simple subtraction would indicate a large movement in the opposite direction. For example a movement from 0.9 to 0.1 would appear as a movement of -0.8, when a movement of +0.2 is much more likely. As such, a change in position should be calculated taking this into account. Here is an example of how to do the calculation in C:

static void CCONV
onTouchHandler(PhidgetCapacitiveTouchHandle ch, void *ctx, double touchValue) {			

   double change = (touchValue - oldPos);  
   static double oldPos;

   if (change > 0.5)
      change -= 1;
   else if (change < -0.5)
      change += 1;

   oldPos = touchValue;
