Documentation: Post a reflection and image of the amp circuit on the breadboard
I really understand the led part. Power comes in from the battery into the power line, it goes into the capacitor filling it. Then the electricity in the full capacitor goes into the resistory which damplens the power so that when the electricity reaches the LED it does not burn out. From the LED the electricity flows through to the ground line where it goes back into the ground of the battery.
Something I am completely baffled by is the regulator. It seems like its not at all useful. For example, its clear that the potentiometer is for regulating flow of electricity, and the soldered audio jack is for connecting your device to the integrated circuit breakout board. However, it is unclear what the regulator does. According to goolge Gemini, similar to the resistor for the LED, the regulator regulates the voltage going to the speakers and makes the sound quality good.
