Arduino ile trafik lambası yapmak için kullanılabilecek bazı kodlar şunlardır: Basit trafik lambası kodu: ```cpp int red = 10; int yellow = 9; int green = 8; void setup() { pinMode(red, OUTPUT); pinMode(yellow, OUTPUT); pinMode(green, OUTPUT); } void loop() { changeLights(); delay(15000); } void changeLights() { // green off, yellow on for 3 seconds digitalWrite(green, LOW); digitalWrite(yellow, HIGH); delay(3000); // turn off yellow, then turn red on for 5 seconds digitalWrite(yellow, LOW); digitalWrite(red, HIGH); delay(5000); // red and yellow on for 2 seconds (red is already on though) digitalWrite(yellow, HIGH); delay(2000); // turn off red and yellow, then turn on green digitalWrite(yellow, LOW); digitalWrite(red, LOW); digitalWrite(green, HIGH); delay(3000); } ``` Yaya geçidi olan trafik lambası kodu: ```cpp // Yaya trafik lambası pinleri int redPedestrian = 10; int greenPedestrian = 9; // Buton pini int buttonPin = 2; void setup() { // Yaya trafiğini başlat digitalWrite(redPedestrian, LOW); digitalWrite(greenPedestrian, HIGH); delay(5000); // Yaya trafiğini durdur digitalWrite(greenPedestrian, LOW); digitalWrite(redPedestrian, HIGH); // Araç trafiğini yeniden başlat digitalWrite(redCar, LOW); digitalWrite(yellowCar, HIGH); delay(2000); }
