Circuit Documentation

Summary

This circuit consists of an Arduino UNO microcontroller, a pushbutton, a red LED, and two resistors. The circuit is designed to interact with the pushbutton and control the LED based on the button's state. The Arduino UNO is programmed to handle the input from the pushbutton and output signals to the LED.

Code Documentation

Arduino UNO Code

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

This code is a basic template for the Arduino UNO. The setup() function is where you initialize your settings, and the loop() function is where the main code runs repeatedly. In this template, no specific functionality is implemented yet.
