Need a user-friendly control panel for your Phidgets project? Look no further than the Touch Wheel Phidget. This user interface board 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 board has four touch buttons and one fully-functional scroll wheel pad. Whenever a button or the scroll wheel is initially touched, an event is fired in software, allowing you to react immediately to the change. The scroll wheel also generates an event whenever your finger’s position changes as you slide it across the wheel. You can also adjust the sensitivity of the board to avoid missed touches or unintentional touches.
