How to use rotator encoder for measurement of shaft rotation and position. B falling, A low . In previous tutorials we've outlined temperature sensing, PIR motion controllers and buttons and switches, all of which can plug directly into the Raspberry Pi's GPIO ports. Hi! I have a 400ppr, max 330 rpm, 2 phase, rotary encoder. 3V so as not to damage \$\begingroup\$ There is no positional "rest point" for such a device, any mention of that you are seeing is a holdover from the fact that it is a closed loop position device with a servo amp chip intended for that purpose, which has instead been hacked by the manufacturer or seller to disconnect the feedback potentiomater from the shaft and turn it into a crudely speed controlled device ALL the Pi GPIO are 3V3. These encoders are coupled by the rotor to the measured shaft through a separate coupling that compensates axial motion and misalignment between the encoder shaft and measured shaft. pi4j rotary encoder
