ULN2003a Amblone v2
Rough layout for Ambilight clone based on amblone.com and using 2x ULN2003a
|
Read steps at amblone.com and grab the software also. Layout is simple, requires a 12v 1 amp DC power supply and an Arduino Mega. If you can't get any ULN2003a chips then the ds2003cn will work. Updated PCB and schematic |

Hi, I have just made your schematic and it doesn't work. I'm using two ULN2003A from ST Microelectronics (http://www.datasheetcatalog.org/datasheet2/f/0c6x6a46ig46qlxf3j2qsaii8o3y.pdf) and this is a photo of my protoboard: http://img860.imageshack.us/img860/3403/img75951024x768.jpg Can you see something wrong? I already have one npn pcb working, but i wanted to try your simpler schematic, and I can't get it work! Thanks.
