not really. you can issue serial line characters to the desktop PC from the HB (see the FAQ), but IC cannot display them. so, for interactive development, it won't work. but if you can quit IC and run a terminal emulator program on your PC (e.g., (...)

Your 16 LED resistors combine to make Req = 1/( 16 x (1/82)) = 5.125 ohms. So your LEDs are drawing just (...) (26 years ago, 1-Jan-99, to lugnet.robotics.handyboard)
