If you have a device that uses the handyboard supply to generate voltages
then just voltage divide the output to the correct 0-5v and input on the
analog ports. If you are using phototransistors or something similar there
are lots of photo circuits in "the robot builders bonanza" avaliable from
the robotstore (www.robotstore.com) or a bookstore (publishers are low on
supply per bookstop).

| I understand how a photoresistor that varies in restistance can be connected to the analog inputs. But what about the photelectric elements that generate voltages varying with light. (27 years ago, 3-Apr-97, to lugnet.robotics.handyboard)
