I salvaged this touchpad from an old laptop and I would like some ideas for using it, I thought about using it as a light dimmer for two sets of lights. Does anyone know how it works? I'm sort of a newbie but I'm willing to learn.
Where can I find its data sheet? Here's the print on the back
ALPS 94v-0 JCI-S1S H 56AAA1865C
(in case the images aren't clear)
There is a small IC under the tape :
The touchpad came from an old Acer laptop, I don't remember the specific model anymore -- very old, AMD Athlon and 1 GB RAM and a floppy drive old.
