Introduction
|
|
------------
|
|
|
|
Usual servos can turn about 180° (90° in both directions from zero point).
|
|
There are some rare servos with 270° turn. If you use a 180° type you may turn it 90° to the left or to the right.
|
|
|
|
.. danger::
|
|
Trying to turn a servo more then what it can handle will run the servo against a stopper inside the gear.
|
|
As ESP Easy tries to go further the servo starts humming and gets hot, it will die over time.
|
|
|
|
The third type "continuous turn servo" is not supported at this time.

Setup
|
|
-----
|
|
|
|
No device is needed, generally you use rules to activate servos, or you send commands to activate them. Below you
|
|
find more information on how to do this.
|
|

|
Rules examples
|
|
--------------
|
|
|
|
.. code-block:: none
|
|
|
|
On Switch#State Do
|
|
if %eventvalue1%=1
|
|
Servo,1,12,-45
|
|
Servo,2,14,45
|
|
else
|
|
Servo,1,12,0
|
|
Servo,2,14,0
|
|
endif
|
|
EndOn
|
|
|
|
This rule will tilt the servos 45° when the button is pressed, and it'll go back to 0 once released.
|
|
|
|
.. note::
|
|
Events may be handled from an event queue, so by the time the event is being handled, the state of the switch can already be different.
|
|
Therefore it is best to use the state of the switch at the time the event was generated,using ``%eventvalue1%`` .
