🚦 Arduino Traffic Light Project 🚥 I built a simple traffic signal system using an Arduino Uno, 3 LEDs (Green, Yellow, Red), and 220Ω resistors. The program makes the two traffic lights work alternately, just like a real intersection. 🔧 Hardware used: Arduino Uno Green, Yellow, Red LEDs × 2 220Ω resistors × 3 Breadboard & jumper wires 💻 Code: // ===== LED Pin Definitions ===== int greenLED = 2; // Signal 1 Green int yellowLED = 3; // Signal 1 Yellow int redLED = 4; // Signal 1 Red int green1L
