hb-25 motor controller awsome

when connecting the motor controller in mode 2 do i still need to use two power sources (one for each motor controller) or just connect one to one motor controlller?

I'am using a 12v 4.2 HA lead acid power source is it alright? i think it is for the specs say it can handle up to 35A just need a confirmation.

Thank for all the replies in advance. Have a good one!

    Hello,

    ·· You don't need two power sources, but you do need power to both modules.· You can connect the power in parallel to both HB-25 Controllers.· I hope this helps.· Take care.

    The demo code we have posted should help you with that.· The HB-25 uses servo-compatible pulses in the range 1 ms to 2 ms with 1.5 ms being stopped.· The closer you are to 1.5 ms the slower the motor will be.· Take care.

    How can I control the motor forward, backward and break?

    Think of 1.5 ms as stop/break
    1 ms as full speed in one direction (lets say Forward)
    and 2 ms as full speed in the other direction (Reverse)

    so a 1.25 ms pulsewidth would = half speed forward
    and a 1.75 ms pulsewidth would be half speed in reverse

    This is just an example, if your motor leads are reversed then between 1 and 1.5 would be reverse and between 1.5 and 2 would be forward.

    Hope this makes sense.

    Which BASIC Stamp are you using?
