Circuit Documentation
Summary of the Circuit
This circuit consists of an Arduino Nano microcontroller, a two-pin red LED, a sound sensor, and a resistor. The Arduino Nano serves as the central processing unit, controlling the LED based on the input from the sound sensor. The sound sensor detects noise levels and provides analog output to the Arduino. The LED acts as an indicator, and the resistor is used to limit the current to the LED to prevent damage.

Documented Code
No code has been provided for the microcontroller. Typically, this section would include the embedded code written for the Arduino Nano, detailing the functionality and logic used to control the LED based on the sound sensor's input. Since no code is available, this section remains empty. If code becomes available, it should be documented here with comments explaining the purpose and functionality of each section of the code.
