 ### Hardware wiring
 Theoretically 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.

 ### Configuration
 In order to use the PWM actuator, you need to configure which pins the PWM output channels will be connected to.

 They can be defined in the `build_flags` section of the env, or by directly editing `config_PWM.h`.
