I have purchased the BS2sx, the Mini-dual H-bridge and the twin motor
gear box from Mondo-tronics. I put them all together, but i'm having
trouble make the motors turn at the same time. i put the gear box
together in Low speed so that i could turn the gears seperately. i
have the connections right(i think) with motor one hooked up to P0
and P1 and motor two hooked up to P7 and P8. i wrote the following
simple program to test the system.

output 0
output 1
output 7
output 8


again:

out0 = 0
out1 = 1
out7 = 1
out8 = 0
pause 250

goto again

when i run it this way, the motors make a quiet buzzing noise, but do
not turn. if i remove the output 7 and output 8 lines, motor 1 runs
fine(either direction) and if i remove the output 0 and output 1
lines, motor two turns fine. but with all four outputs it will not
turn either.

What am i doing wrong?

thanks!! tom
