🚀 Quick Setup
Materials List
- 1 Arduino Uno
- 3 LEDs (red, yellow, green)
- 3 Resistors (220 ohm)
- 1 Breadboard
- Jumper wires
Assembling
1. Connect the LEDs to the breadboard.
2. Connect the resistors to the LEDs.
3. Connect the jumper wires from the breadboard to the Arduino Uno pins.
4. Connect the red LED to pin 9, yellow LED to pin 10, and green LED to pin 11.
Arduino Code & Libraries
No libraries required. arduino
// Define the pin numbers for the LEDs
const int redLed = 9;
const int yellowLed = 10;
const int greenLed = 11;
void setup() {
// Set the LED pins as output
pinMode(redLed, OUTPUT);
pinMode(yellowLed, OUTPUT);
pinMode(greenLed, OUTPUT);
} void loop() {
// Red light for 5 seconds
digitalWrite(redLed, HIGH);
delay(5000);
digitalWrite(redLed, LOW);
// Yellow light for 2 seconds digitalWrite(yellowLed, HIGH);
delay(2000);
digitalWrite(yellowLed, LOW);
// Green light for 5 seconds
digitalWrite(greenLed, HIGH);
delay(5000);
digitalWrite(greenLed, LOW);
