I purchased the ssd1331 oled screen after I saw the lego tutorial using that screen on your site. I wired it up to my arduino and the screen is extremely dark. The test program and the bitmap program both worked (no errors in the serial monitor) and displayed, but the screen is too dim to see unless it's in a dark room with no windows. My assumption is that the screen ought to be significantly brighter. I checked the wiring twice now, and it looks to be right. I hit all the solder points on the terminals again, and they are good joints. Do you have any idea why the screen might be that dark? Is there a problem with how I'm setting it up, or is the screen maybe just dead on arrival?
Thanks for the help,
