Ok, before we get into how to code my idea. Is it even possible to connect an lcd computer monitor to the arduino and control its brightness, or turn it on and off... I think for turning it on and off it should be possible by splitting the positive and ground...right!?
I want to have an image on the lcd and eventually use a distance senesor to turn the brightness all the way up and down. ON/Off would suffice, but there will probably be a longer pause between which i would like to avoid.
I want to plug in a computer lcd monitor (15") into the arduino and have a picture shown on the screen - using a distance sensor, Id like the arduino to use the distance readings to adjust the brightness of the computer monitor from the brightness all the way down, with a specific distance, (look like monitor off, or actually turn monitor off) to brightness all the way up, with another distance reading.
Is this possible? I know with the "magic mirror kit" they are able to play flash animations on the lcd monitor using an arduino microcontroller. But i just want a still image, and then to turn off the monitor using the distance sensor.
