Dimming or Turning OFF the Button LED

Most of the time you will probably not need to adjust the LED brightness. For the times you do need to dim the LED or turn it off you just need to edit the "led_brightness" parameter.

"led_brightness": 10

To turn the LED off, edit parameter "led_brightness" to a value of 0.

The brightness value range is 1-10, with 1 being the dimmest and 10 the brightest.

When the image capture sequence is on, the LED will fade between the max brightness set by the "led_brightness" parameter and a value of 1 (lowest but not off). For example, if "led_brightness" is set to 10 (default), it will fade between 10 and 1 (10-1-10-1...).
