Project 1: Blinking LEDDifficulty Level: Beginner Components RequiredComponent Quantity DescriptionArduino Uno 1 Main microcontroller boardLED (any color) 1 Light Emitting DiodeResistor 1 220%u03a9 (to protect LED)Breadboard 1 For easy circuit connectionsJumper Wires 3%u20134 To connect components to Arduino Circuit Schematic%u2022 Connect LED anode (+, longer leg) %u2192 Arduino pin 13 through a 220%u03a9 resistor.%u2022 Connect LED cathode (%u2013, shorter leg) %u2192 GND on Arduino. Arduino Code Explanation of Codeint ledPin = 13; %u2192 tells Arduino that LED is connected to pin 13.pinMode(ledPin, OUTPUT); %u2192 sets the pin as output (to send voltage).In the loop():digitalWrite(ledPin, HIGH); %u2192 turns LED ON.delay(1000); %u2192 keeps it ON for 1 second.digitalWrite(ledPin, LOW); %u2192 turns LED OFF.delay(1000); %u2192 keeps it OFF for 1 second.This repeats forever %u2192 LED blinks continuously. Expected Output / Learning Outcome LED blinks ON for 1 second, OFF for 1 second.
