Signal wire (yellow wire), red wire (power wire), brown (ground wire)

The control of the steering gear generally requires a time base pulse of about 20ms. The high-level part of the pulse is generally the angle control pulse part in the range of 0.5ms-2.5ms, with a total interval of 2ms. Taking the 180 degree angle servo as an example, the corresponding control relationship is as follows:

0.5ms--------------0 degrees;

1.0ms------------45 degrees;

1.5ms------------90 degrees;

2.0ms-----------135 degrees;

2.5ms-----------180 degrees;

360-degree steering gear: actually equivalent to a geared motor with infinitely variable speed, which can control speed and direction. There is no 0-360 degree angle control function. The control method is the same as the control signal of general steering gear. It is a suitable power source for Wali modification (When the high level is 1 millisecond to 1.5 milliseconds, the steering gear rotates forward (the fastest forward rotation speed is 1 millisecond, the closer to 1.5 milliseconds, the slower, the steering gear stops rotating at 1.5 milliseconds), the high level is 1.5 milliseconds to 2 The steering gear reverses in milliseconds (the steering gear stops rotating at 1.5 milliseconds, the closer it is to 2 milliseconds, the faster it reverses, and it reverses at the fastest speed at 2 milliseconds).
