Hi Haltptit,
I had forgotten you. Sorry.
This is what you were looking for.
The higher the value value, the slower the motor will go. The value 1023 = Stop. Towards 650, it does not move but the current always passes.
The value 0, I drive fast enough but I do not know if it can go faster.
It takes 2 outlets to steer the motor. This corresponds to the 2 sides that the engine can turn. I did not try to send in 2 outputs at the same time because I guess the engine will not split into 2.
I will not put any links here because I buy the engines and components on AliExpress and it’s really not very expensive. Conclusion: ServoMotor and Motor with HaloCode work.
If you want to know how to connect, you ask on the forum, I will indicate it in another post.
