Hello all,
I am planning to build a custom Android HUD for my car. It will be build into a 3 cm high case, where the screen will lay on top of the case, so it will reflect in the windshield. Inside the case there will be an Android mini pc connected to the screen by HDMI. All good so far, the only problem is that I need to find a way to have the display dim itself when the ambient light is getting dark(er), so that the screen is bright in daylight, but dim at night.
Can I (just) add a light sensor to the LCD controllerboard and if yes, what is the best and ofcourse cheapest way to do that or should I approach this different?
Thank you in advance.
