# PWM outputs
v2 Usermod to add generic PWM outputs to WLED. Usermode could be used to control servo motors, LED brightness or any other device controlled by PWM signal.
## Installation
Add the compile-time option `-D USERMOD_PWM_OUTPUTS` to your `platformio.ini` (or `platformio_override.ini`). By default upt to 3 PWM outputs could be configured, to increase that limit add build argument `-D USERMOD_PWM_OUTPUT_PINS=10` (replace 10 by desired amount).
Currently only ESP32 is supported.
## Configuration
By default PWM outputs are disabled, navigate to Usermods settings and configure desired PWM pins and frequencies.
## Usage
If PWM output is configured, it starts to publish its duty cycle value (0-1) both to state JSON and to info JSON (visible in UI info panel). To set PWM duty cycle, use JSON api (over HTTP or over Serial)
```json
{"pwm_0": 0.0, "pwm_1": 0.1, ...}
```
