 Jeff suggested that I should go over some tips on how to keep a breadboard tidy, and I agree. It's a good idea. I personally don't get too fancy. I just focus on the jumper wires. Color coding always helps. Black for ground, red for positive, but cutting custom-length jumpers makes the biggest difference. I strip about 8 millimeters from one end of a piece of solid-core wire, insert it into the starting node, lay the wire down a path to its destination node, add an extra 15 millimeters or so, cut, strip another 8 millimeter lead, insert, done. Now if I wanted to get really fancy, I could go pre-plan the whole layout and fritzing. The app is perfect for that. But it's a breadboard. It's temporary, so don't obsess.
