Sensor to measure rotations

Hallo all,

I am working on a robot and in search of a sensor that realizes the angle of rotation of the limbs.I would appriciate any form of suggestion.

Thank you

Would you mind invesing 5 minutes in resaearch before posting?

Flex sensor, encoder, pot.

Thank you

Make that an absolute encoder, note.

Get the Arduino cookbook by Michael Margolis and read it. You will find on line many videos etc showing the Arduino and how to do use it some of it may be what you want. This additional information will go a long way in getting your problem solved. There are also many videos showing how to read a data sheet. Once you get past this you then need to select your sensors and actuators. At that point you start on the hardware design and write your software.

What is moving the limbs in the first place? Sure it must be some logic that exactly knows the position of the limbs.
