I have and Uno with a top-plugged SainSmart proto shield. There are 2 LEDs on the proto shield, but I don't know how to make use of these LEDs in a sketch. Are they directly controllable out-of-the-box, or do I first need to solder the LED leads to analog/digital (not sure which) outputs on the proto shield to make them accessible? Thanks.
Hm, can't seem to find the schematic although looking at the board, my guess would be to load on blink to your arduino and see if the protoshield lights up any leds.
