We started to solder elements of our circuit to printed circuit board. We started by creating a hand-drawn diagram of where we were anticipating placing the various elements in our circuit, placing the buzzer in its location first (because it is the largest element in our circuit). We then placed the remainder of our circuit elements in the drawing, anticipating both the spatial requirements and orientation necessary to building a compact, operational circuit. After doing the initial diagramming, we soldered on our 51K, 22K, and one of our 10K resistors. We also soldered in an IC socket for the op-amp so that we wouldn't need to risk burning it out. These were followed by a jumper wire running from pin 3 of the op-amp socket to ground and then the sixteen 1N4148 diodes in series with each other and in series after the 10K resistor as it delivers current and voltage to the trigger pin of the 555 timer. Our next step is to finish soldering everything and ensuring that it works once everything is attached to the PC board.
