Potentiometer Angle Measurement

Additionally this example demonstrates the use of the board.

Potentiometer angle measurement.

Encoders with optical and magnetic technology basic considerations for product decisions. A potentiometer is a three terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. Potentiometers are often used as a position or angle transducer to measure distances or angles. The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential voltage.

The measuring range of the angle that a sensor must measure is of particular importance when selecting the technology. If only two terminals are used one end and the wiper it acts as a variable resistor or rheostat. Absolute encoder output the actual position on the shaft and are used to measure absolute angle. This is because ranges up to 360 are covered with singleturn sensors and ranges above that with.

Incremental encoders output the increment of angle on the shaft and used to measure angular motion. In this example we will demonstrate how to use an analog potentiometer and how to display the reading in the serial monitor. Measuring angle by potentiometer. I really just wanted to see if this works so i am just approximating the angle and look at the resistance at 0 90 180 and.

The device is for extreme outdoor purposes and repeatably needs to define angle measurements within one degree. This is another example of using the analog pins for input and using the serial connection to send data to a usb connected pc. The correct device to measure angle is called a rotary encoder. In professional audio equipment faders are often used.

Position or angle transducer. All i am going to do is see how the resistance changes with the angle. For balance control a dual gang potentiometer can be used where on gang has a logarithmic taper and the other gang has an inverse logarithmic taper.
