servo_switch

servo_switch(name, pin,
    on_angle, off_angle, return_angle,
    on_command="on", off_command="off",
    turn_time_ms=700,
    min_us=600, max_us=2400);

Create a new servo motor controller acting as a switch. name will be appended to the mqtt topic and a set appended to send commands to.

Parameters

  • name: the name it can be addressed via MQTT in the network. Inside the code it can be addressed via IN(name).
  • pin: the gpiopin
  • on_angle/off_angle: respective angles for on/off postions
  • return_angle: a medium angle to return to after pushing to on/off position (if not given as parameter, this feature is not used and motor does not return here)
  • on_command/off_command: what needs to be sent to turn the motor to on/off position
  • turn_time_ms: how long to give the motor in ms to reach its position before stopping power
  • min_us, max_us: values controlling the motor settings

Example

servo_switch(m1, D4, 0, 180, 90);

Now the motor can be controlled via sending to the mqtt-broker to the topic node_topic/m1/set the command on or off.
