| | | What was/is the purpose of the IR Subsystem on the Handy board. What is the difference between the Sharp Demodulator and the one you get from Radio Shack. How do you use the onboard IR demodulator as a digital input. Are there different kinds of IR (...) (27 years ago, 27-Mar-97, to lugnet.robotics.handyboard)

Is the Sharp IS1U60 an IR demodulator, or simply and IR receiver? I (...) (27 years ago, 28-Mar-97, to lugnet.robotics.handyboard)
