<p class='vspace'></p><h2>write()</h2>
|
||
|
|
<h4>Description</h4>
|
||
|
|
<p>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).
|
||
|

|
||
|
|
<p class='vspace'></p><h4>Syntax</h4>
|
||
|
|
<p><em>servo</em>.write(angle)
|
||
|
|
</p>
|
||
|
|
<p class='vspace'></p><h4>Parameters</h4>
|
||
|
|
<p>servo: a variable of type Servo
|
||
|
|
</p>
|
||
|
|
<p class='vspace'></p><p>angle: the value to write to the servo, from 0 to 180
