Circuit Documentation

Summary

This circuit consists of an Arduino UNO microcontroller connected to four red LEDs. The LEDs are controlled by the digital pins of the Arduino, and all LEDs share a common ground connection.

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 you place the code that you want to run repeatedly. In this case, the code is currently empty and can be modified to control the LEDs as needed.
