| (...) The motor outputs give a square wave of 1/8 up to 8/8 of a cycle. You can use a counter running at 8x the cycle frequency to measure how many eighths the output is giving, and light an LED accordingly. For the magnetic sensor, I suggest (...)

This works pretty well, since with the reflection of the light of the LED, black and white can be easily recognised. Then the ambient light has not a big influence. (...)

|  |  | Real-world interfacing to RCX:  LEDs and magnetic sensor 
 | 
 | 
| I would like to be able to drive one or two banks of 7-8 LEDs off of the motor ports on the RCX. I know that there is a winker board that senses the motor level to determine what pattern to display. Can this be accomplished otherwise? I also want to (...)
