servo

servo(name, pin, min_us=600, max_us=2400,
    turn_time_ms=700);

Create a new servo motor controller. name will be appended to the mqtt topic and a set appended to send angles 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
  • freq, min_us, max_us:
    values controlling the start and end motor timing settings
  • turn_time_ms: how long to give the motor in ms to reach its position before stopping power

Example

servo(m1, D4);

Now the motor can be controlled via sending to the mqtt-broker to the topic "node_topic/m1/set" the angle to turn the motor to.
