Um, I have a small Electrical problem... when you look at the Schematic
http://www.usfirst.org/uploadedFiles...0Schematic.pdf
It shows what is supposed to be what. When I measure their resistance, R4 is supposed to be 1K ohm, but on one of the boards it says .350K ohms, and on the other one it say it is .450K ohms. So what the hell is going on?
Also, one R3 is 1M Ohm Resistance, while another R3 is only 1k Ohm.
For some reason our boards seem to be messed up beyond belief, or am I just freaking out?
