I've got a light control board that will send different light patterns to 10 number 47 incandescent light bulbs. To activate the patterns I need to ground 1 of the header pins on the board. The pattern will stop when the ground is removed. There are 2 rows of headder pins. 1 row is ground and the other activates each pattern. I can use a simple switch to do this. Can EZb do this for me? If so how do I hook it up? If not is there anything else I can use that will let EZb ground these pins?
