    Use an electronic CAD tool. The diagram doesn't make any sense to me.

    let me explain it
    its a h brigde with a motor at center
    h bridge is either made of relays or mosfets
    (see it will resemble something like this with some extras
    http://www.pyroelectro.com/tutorials.../schematic.png
    http://www.pyroelectro.com/tutorials...g/on_dir_2.png
    )

    the directions inputs are used for driving the motors in forward and rev (1 0 and 0 1 digital)
    and pwm in is used for speed control.

    everything over there is fully documented.

    it makes a perfect sense. its block diagram how can i draw it in a CAD. one all my doubts are cleared, i will convert it into a schematic.

    What's wrong is drawing a schematic from day 1? Why do you need the block diagram?

    sorry i couldnt reply. i was away from my place.

    can anyone just verify the block diagram
    http://www.roboticsindia.com/attachm...4&d=1319966848

    check whether the concept is right for the motor control with H bridge mosfet/relay with pwm.
    i will post the full schematic few days later.
