[Coach Seb]

Hi everyone,

we have a arm that tilt up and down and we would like the arm to stay in the position that the controller stop.

It is a neverest 40 with 40 tooth gear on motor shaft and 120 gear on the arm lifting device. The motor can handle the motion but when we reach the desired position, it fall back due to the weight of the arm.

Is there a way to program the motor so it stay in position?

We are using MIT APPInventor.

Thanks

Sebastien
