| Hi John, It depends on what kind of circuit your infrared sensors are in. An infrared diode or transistor can not be hooked directly into the HB. They have to be biased properly and the signal amplified to be compatible with either the digital or (...) (26 years ago, 25-Nov-98, to lugnet.robotics.handyboard)
