I have a question regarding absolute rotary encoders. I need a rotary encoder to measure the angle an axis is
tilted. The axis is not supposed to move around in circles. It will just be able to turn 180 degrees clockwise and
180 degrees counterclockwise.The rotary encoder mounted on the axis is supposed to give me the current angular position of the axis related to a fixed, origin position. The encoder should also be able to tell if the axis has been tilted clockwise or counterclockwise from the origin position. (I will use an Arduino platform to interpret the signals from the encoder) Which rotary encoder is best to use? Or should I use another form of component for angular measuring? As written before, it should be easy to connect and use with the arduino platform.
