Hi,
Can anyone let me know if i can fade in/out using the Litex Spare Battery Case mini controller for the item below:

Either
White LED Backlight Module - Small 12mm x 40mm

Or
Normal LED.

If you want to fade in/out a regular LED then you have to resort to PWM.

HI there,
I was asking because the product https://www.adafruit.com/products/1398 does say it can have a simple in built controller. Not sure i can mod it without the use of a PWM?

The battery pack has a simple controller that switches between a few modes: all on, fast blink, slow blink, and a slow fade in and out.

It has a controller, so the controller must be using a PWM to acheive the fade.
