    I'm trying to use my sim wind in simtools3, but without success, I use a shild L293D engine, just a cooler connected to the M1, any idea how I can get a script that works?

    What script did you used to use buddy?
    We can probably find how to drive it in v3 is all.

    I tried to use the one posted in the discussion, but I saw that the motor shield is different, I would like to know if there is any script for my motor shield for just one cooler connected to M1

    What size diode do I need to installed in between the motors if running the 12V 6A 270CFM inline Fan? I circled that in Orange

    Probably depends on the size of fans you want to use, but I can't see a fan outputting that much reverse power when the power goes off.
    Here is a link to the article the pic came from.
    http://adam-meyer.com/arduino/rfp30n06le-arduino
    "We will need a diode fast enough to react to the kickback, and strong enough to take the load. A rectifier diode like the 1N4001 or SB560 should do the job."
    Take care!

    thank you. And if I use a bigger fan then 2A, say the 6A fan bilge inline fan that you’re using in the video, which motor control board would you recommend and do you happen to have a wiring diagram?

    You would simply make this circuit two times, one for each fan buddy.

    Would the fan connect direct to the Arduino board without a motor control board?

    The circuit is your 'motor control board' if you will.
