How to use the B2 controller to control the motor to do some simple movements

1. Determine the servo control type, bus based, and pulse based. I estimate your approximate rate to be pulsed.
2. Confirm that it is pulsed, and confirm the electronic gear. (If you remember correctly by default, the upper computer sends 10000 pulses, and the servo motor rotates for one revolution.).
3. The distance between A-B is calculated based on the electronic ruler, or if the electronic ruler is set, the upper computer can directly send pulses, such as the default electronic tooth. The upper computer sends 5000 pulses, and the servo motor rotates for half a turn.
4. As for speed (10S as described by the owner), it can be calculated based on the distance you move.
