Hi all,
i need some help,
i want to turn a 6inch disk,, to five diffrent spacific spots,
in any rotation/sequence,
stepper,
with a hand-paddle,/push-button for each of the five settings,
,
and/or a computer interface/window,
,
and something to tell me what one of the five im on currently,
,
as a very green electronicaly chalenged soul,

    John,
    I don't know if you can, but maybe you could drill a series of holes on
    your disk with all different sizes and mount a led under the disk, and a
    photo resistor directly above the led and disk. So when the disk turns,
    hole A lets in X amount of light which then tells you which position the
    disk is in. Hooking up five push buttons can be easily hooked up to the
    stamp. And finally, the Bs2 has a great function called debug which will
    lets you send data back to the computer. All of this is covered in the
    Stamp manual, which is a great asset. Hope this helps, and if you need
    any more help email me off list and ill go into more detail. Being a
    newbie I feel I should help [noparse]:)[/noparse]

    -Mike

    If they still have them available, buy one of the
    Parallax 'What's a Microcontroller?' courses. This
    comes with a servo, and all instructions how to
    use it. Put the disk on the servo, add a few
    buttons, follow the instructions, and you should
    be good to go.

    This assumes you already have a BS2 and a Board
    Of Education (BOE). If all you have is a BS2, then
    you can still do this with a RadioShack breadboard,
    but wiring becomes a little more tricky -- and you'll
    need a 7805 linear regulator based power supply.

    Another alternative is to take advantage of their
    $79 homework board offer -- which has the 'What's a
    Microcontroller?' along with a surface mounted BS2
    and a prototype area. You'll still need to add
    an AC/DC adapter (which Parallax sells).

    Duh, I should have thought of servos... much easier.

    Hi John,

    you didn't mention power needed so assuming a light weight disk ?

    a set of 3 optical switches from a couple old mice or old floppy or
    old printers or something would offer a noncontact sensor. you can
    easily use a simple arm to trip each sensor.


    The inputs from your switches then would tell the program which point
    to go to next.


    and you could control a bi-polar stepper with 4 output pins.


    this would be a good learning experience.

    the inputs are simple in as much as you learn about optos and how to
    wire them, and since they are noncontact and board powered, you don't
    have to worry about frying things.

    also, you get to learn about switches, so you manual inputs are just
    an extension of that.


    The stepper part can be simple (4 pins for one motor) so you do not
    have major learning curve there either.

    Now, if you throw high power or high speed, you start to complicate
    things.
