Power and Ground Step 2 of 6

For this project, I used a 9-volt battery to power the CD4093BE and an LM386 op-amp simultaneously. Datasheets for each of these are linked in the next steps.

Experimentally, I interrupted the input voltage line with a 50K potentiometer for gain. I think this could be improved upon by more knowledgable folks, but it does provide a little bit of control over loudness/output.
