 | | Analog/Digital IO
|
| I know this question does not really relate to the handyboard, but does anyone know of a cheap PCI or ISA card for a PC to read analog or digital values? Thanks, Mike Reiling (25 years ago, 3-Feb-00, to lugnet.robotics.handyboard)
| | | | | stepper motor sequence [DAT]
|
| hi all i was trying to connect a uni polar stepper motor with the hb. i was using the stepping sequence given in peter harrison page. A B C D 1 0 0 0 0 0 1 0 0 1 0 0 0 0 0 1 This sequence means that each coil will be energised one by one. and at no (...) (25 years ago, 3-Feb-00, to lugnet.robotics.handyboard)
| | | | | Re: 12V servo motors
|
| Since the HB battery is only 9.6 V, a 12 V motor would most likely draw too much current and pop the circuit breaker (or worse). I don't see why you couldn't power the servos with a separate 12 V battery, though. The HB expansion board is all set up (...) (25 years ago, 2-Feb-00, to lugnet.robotics.handyboard)
| | | | | 12V servo motors
|
| hi, The HB FAQ says to use 6V servo motors connected to the batt supply with a couple of series diodes to reduce the voltage. can i use 12V servos instead? cheers fazal (25 years ago, 2-Feb-00, to lugnet.robotics.handyboard)
| | | | | RE: More servo stuff
|
| Hi. We have a problem with servo as well. When we test one servo motor, it works just fine. But when we test more than one, the speed of each servo decreases. Does anyone have similar problem? Thanks for your help. Damee Choi (25 years ago, 1-Feb-00, to lugnet.robotics.handyboard)
