    Thanks Hannibal,
    The microphone of the smartphone is very sensitive and in the very small garage the sound is amplified .....
    I hadn't noticed the birds in backgound ...:grin

    Hi guys, I'm back ...
    I burned a power supply and on advice I bought 2 Simukit power supplies, hoping they are more robust.
    I had to modify the case because the new power supplies were longer.

    I also added 2 resistors to be inserted in the second sabertooth even though it is only in the motor, perhaps it was the cause of the breakdown of the power supply.
    I had to make a support to raise the arduino board because there was no more space.

    Then I changed the power of the potentiometers, before 5V were taken from sabertooth, now they are taken by arduino.

    I also changed the position of the motors on sabertooth, now the otors 1 and 2 are on sabertooth 1 and the engine 3 on sabertooth 2.

    First test with simtootls.
    In Arduino I uploaded the sketch that Wanegain kindly gave me.
    Only the motor 2 works following the cursor movement in simtools test, the motor 1 and 3 continue to vibrate and do not follow the cursor movement.
    Can you help me .... Thanks
