The PhidgetCircularTouch detects changes in the
capacitance between the on-board electrodes and the object making
contact. The side of the circuit board opposite the connector and
components is the side intended for contact.
The 1016 can be mounted behind a sheet of glass or plastic; The recommended
thickness is 1/8 inch. Use Silicon adhesive when attaching the Phidget
to the material; standing the PhidgetLinearTouch off or creating space
between the separation material and the Phidget can cause false-triggering
to occur. Materials thicker than 1/8" may work, but will require
a larger surface area of contact to ensure proper triggering (i.e.:
two fingers instead of one).
Sliding a finger along the touch sensor varies the Analog Input 0
value from 0 to 1000 in approximately 125 discrete steps. When the
finger is removed, the final measured value is retained. Two Digital
Inputs are used to convey additional information: Digital Input 0
is True when contact is made with the Phidget, and Digital Input 1
is True when a finger or object comes in close proximity to the board.
The Analog Input value is valid when both Digital Inputs are true.
Comes Packaged with:
A 3016 - 120cm Custom USB Cable
A Hardware mounting kit
The PhidgetCircularTouch connects directly to your computer via USB,
and behaves like an InterfaceKit in software.
