We finished soldering our circuit elements to the PC board and tested the circuit, making sure that we had wired it up correctly and that it operated when the leads were placed in water. When we did this, we found something very interesting - not only did the buzzer produce noise at a higher pitch and frequency, it also activated regardless of whether or not the probes were inserted in water. We decided to determine the cause of this phenomenon by replicating the soldered circuit on the breadboard using equivalent parts to determine the cause of this issue. We found that in order for the circuit to work the way we anticipated, we needed to relocate the source of the switch in order to produce an output signal.,
