Use the VDB to prototype different sensors quickly and easily.  The voltage divider circuit is the foundation for any sensor application in robotics.  Robodyssey has taken the work out of prototyping sensors with the VDB.  Terminal block connectors can incorporate a variety of sensors (photo-resistors, thermistors, etc.).   3-pin Motherboard housing connector on one end.   3 wires: red power, black ground, white signal potentiometer wired in series with terminal block connectors.
