motor mount kit/BS2

kwanzimelonhide

I am using the Basic Stamp 2 Homework Board with the Motor Mount Kit and I am running into a problem. I connected the 3 pin header cable from the "+5,Ground,DATA" terminal on the Position Controller to the Homework Board (+5 to Vss, Ground to Vdd, DATA to P12) and suddenly the power turns off on the homework board and I measured the voltage across the Position Controller's Ground and +5 terminals to be 0.714 V. I measured the voltage from Vss to Vdd and the voltage was about +5·V so I know the problem is not with the Homework Board. I unplugged the 12 V power supply from the HB-25's that are powering the motors so I know the problem just involves the Position Controllers. Can anyone think of a possible cause of this?
thanks...

kwanzimelonhide,

Starting a new thread about your problems with the Motor Mount and Position Controller is not going to change the fact that you do not understand what you are doing.

As I said in your other thread:

"From your description of the problems that you have had with the HB25s and the Motor Mount and Controller kit, it sounds like you need to read up on basic dc motor control and battery powered motor circuits.

The Parallax manual for assembly and use of the Motor Mount and Controller kit are some of the best that I have seen and ditto for the HB25s.

Your questions indicate that you may be in over your head and could possibly damage either the HB25s or the Motor Mount controllers if you do not understand how they function and are interconnected.

I suggest you enlist the help of someone who is technically competent with respect to dc motors, batteries/chargers,·pwm motor control·circuits, and the like."

However, based on what you have said, you probably managed to reverse the +5 vdc and Gnd coming from the Homework Board at the Controller connector which shorted the +5 vdc to Gnd and shut down the voltage regulator on the Homework Board.

If you will notice on page 8 of the Motor Mount and Controller kit documentation, it is not "+5,Ground, DATA" at the Controller connector, but "Ground, +5 vdc, DATA".

Like I have said before, you do not have the level of experience required to work with the Motor Mount and Controller kit and will most likely damage the hardware and become very frustrated.

Regards,
TCIII

For your information Tom C., I checked my three simple connections and did not write "+5,Ground, DATA" with the intention of writing them in the order they appear on the 3 pin header so don't make assumptions about problems you don't understand and the experience of people you don't know...and at the time I wrote my previous thread I had nothing hooked up yet, so yes I didn't understand what I was doing and that is why I asked for help. And thanks to some other people who nicely replied back with useful information, I now understand the answers to the questions I asked. I am technically competent and unlike you, socially competent. so don't reply back to me with any more useless arrogant replies.

Ahhhhh.....christmas eve.....the sound of robots with frayed nerv..err.. circuits quarreling around the dinner table.

Merry Christmas my robot obsessed forum members!

I'm pretty certain this would be a wiring problem.

Triple check your connections, one by one, as if your life depended on it and you'll find the issue.

still doesn't work...the only other thing I can think to ask is what the purpose is of the Double RA Header Pins (why is it not a single pin outlet like the one that goes to the HB-25?) I have tried all combinations- one cable in one pin outlet, then one in the other pin outlet, and two cables at once in both pin outlets(connected to the same vdd and vss on the board)...
