servo.writeMicroseconds()

[Servo]

説明

Writes a value in microseconds (uS) to the servo, controlling the shaft accordingly. On a standard servo, this will set the angle of the shaft. On standard servos a parameter value of 1000 is fully counter-clockwise, 2000 is fully clockwise, and 1500 is in the middle.

Note that some manufactures do not follow this standard very closely so that servos often respond to values between 700 and 2300. Feel free to increase these endpoints until the servo no longer continues to increase its range. Note however that attempting to drive a servo past its endpoints (often indicated by a growling sound) is a high-current state and should be avoided.

Continuous-rotation servos will respond to the writeMicrosecond() function in an analogous manner to the write function.

Syntax

Servo myservo;

servo.writeMicroseconds(uS);

Parameters

• servo: a variable of type Servo
• uS: the value of the parameter in microseconds (int)

Example

#include <Servo.h> 
 
Servo myservo;
 
void setup() 
{ 
  myservo.attach(9);
  myservo.writeMicroseconds(1500);  // set servo to mid-point
} 
 
void loop() {}
