Servo and/or Motor control question

ArchiverArchiver Posts: 46,084
edited 2000-10-06 16:58 in General Discussion
Hello,

I'm interested in exploring the use of a servo with
the Parallax Stamp. Could anybody:

1) Point me to some good tutorials?

2) Inform me of the cheapest place to purchase servos
for simple experimentation purposes?

ALSO I eventually want to work with motors, if anyone
has suggestions on learning more about Stamp / Motor
integration, please let me know.

Thanks in advance,

Todd

    RE: [noparse][[/noparse]basicstamps] Servo and/or Motor control question

    Hi Todd,

    goto Parallax's web site to download the robotics manual at their download page.
    http://www.parallaxinc.com/html_files/downloads/download.htm
    This will give you a very good understanding of the servos and how they work with BS-II.

    I do not know much abt interfacing motors with servos. Sorry no info from me there [noparse]:([/noparse]

    The Stamp manual (download from Parallax) has a BS1 experiment called "Fun
    With Trains." It shows how to do software PWM (not the built-in PWM command)
    to control a DC motor through a high-current driver (like the ULN2003). I've
    used it to control small DC motors.

    We have a good tutorial on controlling and modfying servos at:

    The Stamp Project of the Month has a servo project this month. I was
    noticing this month that the project of the month started in December of
    1997! Time flies when you are having fun (or is that Time Flies Like an
    Arrow? Fruit Flies Like a Banana? I always get those mixed up).

    The project is always at http://www.al-williams.com/awce/som.htm

    Hello Todd,

    I have just started experimenting with servos myself. Al Williams
    has been a great help and has much info as well as products to help
    you with your stamping projects.

    As far as finding deals on servos, try www.balsapr.com! I was able
    to find a standard servo for about $8.00 with a futaba connector, I
    think the product number was bp148 standard. For small projects I
    think it's a great deal.

    Good luck!
