Hey I am working on a project for school:
I am integrating a joystick with a mouse, the click buttons will have sensor pads underneath which will determine the X and Y axis.
I need to know how I can sense proximity of a finger (distance of about 4cm) from those pads.
I've looked at the capSense() library and was worried about interference and instability in the sensor readings. Having the two sensors close to each other can be a problem too.
I dont have much budget, do you guys think I can pull this off? Is there a trusty sensor I can buy to pull this off?
