    My Motion Simulator:
    Arduino
    Hi everyone,I'm new to this forum and to the whole world of simulation. I would like to build my simulator with 3 motors and I'm just getting started seeing the documentation for the arduino program and the connections. I don't understand which is the right way to connect the arduino to the IBT-2-H Bridge, I mean, this motor driver needs at least 2 pwm pins, one for one direction and the other one for the opposite direction, and also 2 enable pins. I'm seeing the tutorial thread which has also an image of the schematic for Mode2 (I'll attach the image here to point the right schematic), but seeing the connection between arduino pins and the IBT-2, it seems that one of the 2 pwm pins per each motor is connected to an arduino digital pin with no pwm capabilities. So I'm trying to understand, how would the motor be able to modulate the other direction if it is connected to a digital pin? Thank you in advance


    The schematic i'm referring to is the one under MODE2, showing the wiring for 2 motors
