# Actuators
|
|
## ON OFF
|
|
This module enables to actuate things by giving to a PIN a HIGH or LOW value corresponding to an MQTT topic.
|
|
Example usage: Connect a transistor to power a relay, connect a led...
|
|
|
|
So as to pilot the pin use the following commands with [simple receiving](../upload/pio.md#api):
|
|
|
|
OFF command:
|
|
`mosquitto_pub -t home/OpenMQTTGateway_MEGA/commands/MQTTtoONOFF/setOFF -m 15`
|
|
|
|
ON command
|
|
`mosquitto_pub -t home/OpenMQTTGateway_MEGA/commands/MQTTtoONOFF/setON -m 15`
|
|
|
|
or with [json receiving](../upload/pio.md#api)
|
|
|
|
OFF command:
|
|
`mosquitto_pub -t home/OpenMQTTGateway_MEGA/commands/MQTTtoONOFF -m '{"pin":15,"state":0}'`
|
|
|
|
ON command
|
|
`mosquitto_pub -t home/OpenMQTTGateway_MEGA/commands/MQTTtoONOFF -m '{"pin":15,"state":1}'`
|
|
|
|
## FASTLED
|
|
### The FASTLED module support 2 different operation modes
|
|
1. control one specific RGB LED
|
|
* Set color
|
|
* Set blink
|
|
|
|
2. Start fire animation (Fire2012)
|
|
|
|
### Hardware wiring
|
|
Theoreticaly it should be possible to use every free IO pin. But after some tests only pin D2 works at WEMOS D1. Other platforms can work.
|
|
The default setting use NEOPIXEL (WS2812B). The simplest wiring is direct connect D2 to data pin of LED stripe and connect VCC/GND to power source. You should also add an capacitor.
