+3.3v not connected*
These are the standard connections used by most existing sketches
which read/write SD cards. We'll do some of the wiring/soldering
on the underside, the solder side of the protoboard.
Now we see why stackable headers, with their long pins, are useful.
They provide nice attachment points for hooking on and soldering wires.
Carefully examine the wiring and our soldering for shorts and solder
bridges. Particularlly check for a short between the +5v and ground busses.
Using the ohms function of a multimeter is helpful.
