Ever tear open a potentiometer? If you haven’t, you can still probably guess what’s inside. A streak of resistive material with some kind of contact that moves across it as you rotate the shaft, right ...
Rotary encoders are typicallyused in positioning systems withservo feedback in which the cost of theencoder usually is of minor importance.Encoders, however, are also usedin user interfaces to encode ...
Similar in size and shape to the common panel-mounted potentiometer, the incremental rotary encoder provides an inexpensive ‘digital’ alternative to the analog potentiometer. It is typically used to ...
The electric motor is the fundamental building block of almost all robotic projects but, without some form of feedback, it lacks the precise positional control required for the task. Small servos from ...
Rotary quadrature encoders often are used to command digital potentiometers or digital controllers, and quadrature decoding is typically performed in a programmable device (like an FPGA or ...
