Firmware is those things that are *both*: it's written like software, but you need to perform hardware-style actions to (...) (26 years ago, 1-Dec-98, to lugnet.robotics)

| 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.
