There is a separate 12 volt power line depicted in his picture. This separate power actually drives the display. The Arduino is simply twiddling the control lines which requires very little power.

I remembered messing with Shift Registers using Arduino as well. But I never expected them to be powerful enough to power a 6.5" 7 Segment LED. Very interesting.

I'd like to use 4 7-segments to display a number that a different part of the program comes up with. Could you help me with this please? I'd like to understand it, but I'm still a novice.

I hate to ask. but how would one go about scaling the code up for more displays? I've already figured out how to control these with a pot and was wondering what the scale up process would be?

I have ordered a 2.25" display from digikey that appears from the datasheet to be pretty bright, but if it doesn't work these 6.5" ones might be my next attempt. Thanks!

I'd take them outside for you but weather forecast isn't calling for sun for a few days. I haven’t tried them in the sun but they are fairly bright in my sunny room.

Fri, 24 Jul 2009 04:38:21 +0000 http://deleteaso.com/?p=175#comment-36936 I am considering using these 7-segment displays for an arduino driven backyard scoreboard (for horse shoes, bags, washers, etc.), but I was wondering how visible they would be in the direct sunlight. Have you tried them outside? If so, any information that you could provide regarding how visible they are in the sunlight would be much appreciated. Thanks!
