wheels clockwise and counterclockwise

SAMYTRIX

I have this program


LOW 12
LOW 13

DO
PULSOUT 12, 500
PAUSE 20
PULSOUT 13, 500
PAUSE 20

LOOP

but the wheels go opposite direction, one clockwise and one counterclockwise, however when I use 500ms for one wheel and 1000ms for the other wheel, they both go the same direction, but each wheel's speed is different so bot doesn't go a straight line. What am I doing wrong? thank you

Remember that the servos are "mirrored" so you will have to mirror the control values to get you bot going in one direction (not spinning in place).· The other thing is that there will always be small component variations that we will have to "tune" our code for; don't be concern about this.

Finally, you only need one PAUSE in your code:

Test:
· DO
··· PULSOUT 12, 500
··· PULSOUT 13,·1000
··· PAUSE 20
· LOOP
