Arduino - Servo.write()
Description
Writes a value to the servo, controlling the shaft accordingly. On a standard servo, this will set the angle of the shaft (in degrees), moving the shaft to that orientation. On a continuous rotation servo, this will set the speed of the servo (with 0 being full-speed in one direction, 180 being full speed in the other, and a value near 90 being no movement).
Syntax
servo.write(angle)
Parameters
- servo: a variable of type Servo
- angle: the value to write to the servo, from 0 to 180
