    I’ve recently started testing a Controllino Maxi, but the DC-motors will only turn one direction.

    I’m not that skilled with Arduino, yet. :-)

    How do I use the integrated H-bridge properly?

    And how do I use the analog inputs as digital inputs?

    The setup I want is:

    analog/digital in 1. Run DCmotor1 – Clockwise.

    analog/digital in 2. Run DCmotor1 – Counter clockwise.

    analog/digital in 3. Run DCmotor2 – Clockwise.

    analog/digital in 4. Run DCmotor2 – Counter clockwise.

    Best regards


    -With this setup, the motors only run one direction.


    Which alternative is correct?

    Hello maasoey,

    Sorry … but the MAXI only has high side switches!

    A high side switch is an electronical switch that switches the supply voltage to the output or not.

    A high side switch will not pull the output to ground if “0”.

    Only the CONTROLLINO MEGA has 12 half bridge outputs. A half bridge output will pull the output to GND if “0”. With the CONTROLLINO MEGA it would work!
