| (...) Hi Elizabeth, The red LED serves only as an on/off indicator. And, as it only functions when the battery is fully charged, it is not a very good one. The rest of the LED's are infrared and invisible to the naked eye. One way to "see" the light (...) (19 years ago, 13-Jun-05, to lugnet.robotics.rcx, lugnet.robotics.rcx.robolab)

| Hi, I got a roboball and wished to test it out for my group of kids to do a soccer game. When I first received it, one light bulb was lit. I tested it with the lego light sensor, but no reading. Then I connected it to a 9v . Unfortunately, now, the (...) (19 years ago, 13-Jun-05, to lugnet.robotics.rcx, lugnet.robotics.rcx.robolab)

| (...) 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 (...)

|
| 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 (...)
