Subject: [alt-beam] walker problems...Please help
>Chris, is this what your looking for?
Yup. Thanks.
>Ok, I've bread boarded a working, 6nv microcore. I used LEDs to see
>whats happening, and it appeared to work. so then I rebuilt it, using
>4nvs. Again, it appears to be working with the LEDs. I used two
>74HCT245s to drive two servo motors, and now it stops working! If I
>leave the LEDs in place (am I supposed to leave them or remove them? I
>tried both) then I can see the the two opposite LEDs flash at the same
>time! EG, 1 and 3 flash, then 2 and 4 etc.
>
>If I short out the 1M resistors one at a time, I can move the legs
>through the walking steps, but I have to short the resistors ONE at a
>time.
>
>Whats going on?????????
>
>ANybody that can, please help me! This is my first microcore, and I'm
>still not exactly sure how it works, so I may have just skrewed up.
>Where are you supposed to connect the motor "outs" anyway? I connected
>them to the same place that the LEDs are to be connected to.

>Thanks a LOT in advance
