To convert from 0-3 to 0-5 I would suspect that all you need is a 2N2222 NPN transistor with a couple of resistors to bias it. For example: +5volts 100 ohm resistor collector ---...---0-5 input 0-3v output -----1k resistor ----- base emitter 0volts (...) (28 years ago, 30-Nov-98, to lugnet.robotics.handyboard)

I have a device that uses 0 - 3V logic levels for the data output. What can I do to convert the output to match the 68HC11's 0 - 5V logic level? Thanks for the help, Dave (28 years ago, 30-Nov-98, to lugnet.robotics.handyboard)

These motors are exellent quality and very powerful the gears are metal and the motors does not exed 300 mA @12V stalled. I currently use the same motors on my robot and had no problems at all. I drive them using the motor drivers on the Handy Board (...) (28 years ago, 30-Nov-98, to lugnet.robotics.handyboard)
