Resistive Position Sensors

we have a tendency to aforesaid earlier that a electric eye could be a resistive device. we are able to additionally sense resistance in response to different physical properties, like bending.  The resistance of the device will increase with the number it is bent.  These bend sensors were originally developed for computer game management (for example, Nintendo Powerglove), and are usually quite helpful.  Notice that repeated bending can wear out the detector.  Not astonishingly, a bend detector is way less strong than lightweight sensors, though they use a similar underlying resistive principle.

Potentiometers

These devices are quite common for manual tuning; you have got in all probability seen them in some controls (such as volume and tone on stereos). generally referred to as pots, they permit the user to manually change the resistance. the overall plan is that the device consists of a movable tap on 2 mounted ends. because the tap is affected, the resistance changes.  As you\'ll be able to imagine, the resistance between the 2 ends is mounted, however the resistance between the movable half and either finish varies because the half is affected.  In artificial intelligence, pots are usually accustomed sense and tune position for slippy and rotating mechanisms.
