 | | question about inputs & outputs
|
| ok this is a funky idea, but I've already got some evidence it can work. I *really* need 4 outputs, but I only need 2 inputs for my project. Is there some way, using brickOS (I assume it's impossible without modifying firmware), to reprogram an (...) (20 years ago, 1-Dec-04, to lugnet.robotics)
| | | | | input used as output
|
| ok, sans any response -- Using NQC, I can turn on & off the LED on my light sensor (changing sensor type between LIGHT and NONE). If I attach a motor to the input, it turns at a low power level (a bit less than power=1) if the sensor type is LIGHT. (...) (20 years ago, 7-Dec-04, to lugnet.robotics)

| (...) No, that's an internal limitation of RCX inputs: when configured for active sensors, they provide a 14mA current limited supply. This low current is enough to light a LED or slowly turn a motor, but don't expect to get any significant (...) (20 years ago, 8-Dec-04, to lugnet.robotics)
| | | | | Re: input used as output
|
| well I've decided to go with 2 RCX's anyway. Later I may switch to a non-lego controller ala handyboard, brainstem, etc. Anyway, for the record, the current is also pulsed in order to get the reading from the photoreceptor. I still suspect I could (...) (20 years ago, 9-Dec-04, to lugnet.robotics)
