Cigarette Lighter spark detection using headphone jack

This is part-III of the post series on detecting electromagnetic waves using headphone jack. In this we capture the EMW that emanate from the spark gap junction on a lighter. This is analogous to our gas lighter experiment but conducted at a smaller scale.

We say that this is analogous to the Gas lighter experiment because the waveforms obtained are extremely similar in nature.
