Wiring Details

Arduino UNO

• 5V connected to positive of the 5V Battery
• GND connected to negative of the 5V Battery
• GND connected to cathode of the LED
• D13 connected to pin2 of the Resistor

LED: Two Pin (red)

• cathode connected to GND of the Arduino UNO
• anode connected to pin1 of the Resistor

5V Battery

• positive connected to 5V of the Arduino UNO
• negative connected to GND of the Arduino UNO

Resistor

• pin1 connected to anode of the LED
• pin2 connected to D13 of the Arduino UNO

Code

Arduino UNO Code (sketch.ino)

void setup() {
  // put your setup code here, to run once:
  pinMode(13, OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:
  digitalWrite(13, HIGH);
  delay(1000);
  digitalWrite(13, LOW);
  delay(1000);
}

This code sets up pin 13 as an output and toggles it high and low every second, causing the LED to blink.
