In Lieu of a Breadboard: PCB LED Test Harness

PCB LED Test BoardHere is a project idea for some of you. If you are anything like me and you are experimenting with an Arduino or TI Launchpad for the purposes of your model railroad, then you likely find yourself adding and removing LEDs and associated resistors to/from breadboards over and over again. So it dawned on me: Why not solder some LEDs and appropriate resistors for a 3.3V source onto a spare PCB project board and slap some headers on there? Well, since I was waiting for some parts for other MSP430 projects, I did just that!
