SoftPot Membrane Potentiometer - 100mm
These are very thin variable potentiometers. By pressing down on various parts of the strip, the resistance linearly changes from 100Ohms to 10,000Ohms allowing the user to very accurately calculate the relative position on the strip. Can be used as an accurate positional indicator for CNC head positioning, variable user input (volume level input for example), straight user input (multiple button areas translate to given resistance levels), and many other applications.
Unit comes with adhesive backing. Connector is 0.1" spaced and bread board friendly.
Note: These potentiometers work great with a finger, or stylus. For premium repeatability, the wiper listed below is perfect for machine and object positioning.

Equip your Arduino project with a sliding soft potentiometer to monitor position or adding linear control to your project.
Core Skill: Electrical Prototyping
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Noob - You don't need to reference a datasheet, but you will need to know basic power requirements.

These are great, but one note of caution: The pins are NOT at right angles to the rest of the potentiometer, so you cannot plug it into a breadboard that's on the same table as the softpot. Also, they're pretty short, so I can't think of any way to attach them at all. However, they are really fun to play around with.
I've found wire-wrap to be an excellent way to extend the leads of anything breadboardable. Much more permanent and less messy than alligator clips but less bother than solder.
