Which H-bridge? How is it connected exactly (please post circuit diagram)? What voltages do you measure on input/output sides and on the signal and other control pins?
L298N... I connect the positive and negative of the motor on out3 and 4... IN3 and 4 went to D7 and D8 of an arduino nano. ENB went to D6.
+12V and ground on the L298N connected to 4 AA batteries.
I left the signal port disconnected since theoretically it only counts the rotations... This way I think the motor should run like a regular DC. But I tried it anyway without any result.

Hi,
Did you google fischertechnik motor arduino
Hello, yes I did... Did you?
