To start off, I'll say that the backpack is a great product and it couldn't be easier to use.
The backpack allows you to set the display's brightness (eg. Arduino lib's setBrightness()
fcn) from 0 to 0x0f.
Unfortunately, the minimum setting (0) is still quite bright - excessively bright in a dark room.
I was hoping to use it on my bedside table, like an alarm clock, but it's way too bright for that.
Given that this is probably just a PWM thing, why not allow the user to set the duty cycle between 0% and 100% ?
