 Based on my experience coaching basketball and robotics, there is no doubt in my mind that if a sports coach receives $x then a robotics coach should, too. - dtengineering [more] |

Re: Attaching LED's to OI joystick ports?
I have not confirmed this but I believe that the OI has an internal LED driver of 10mA (something like the STP16C596 perhaps).
The nice thing about constant current LED drivers is that they provide 10mA regardless of the LED's internal voltage drop, resistance, etc. You can test this out by stacking 2 LED's series. If 2 LED's in series still pull 10mA just like the 1 LED does, then odds are IFI isn't just using an internal resistor to limit current. Joe J. |
