I'm searching for touch sliders that I can use with my arduino. Unfortunately I can't find a single one to buy or built. There are membrane potentiometer like This, but they are to inaccurately for my use case. I need to differentiate 128 values in 40-60mm width.
Here are a few examples for what I'm searching:
I only found a development board for a capacitive touch microcontroller, which has a touch slider. http://de.mouser.com/ProductDetail/Silicon-Labs/F990SLIDEREK/?qs=cvlTIYUSnFZ7OVkvy6CY1g==
Are there really no touch sliders?
