Traffic Light

Traffic Light

AX22-0024

A PCB that looks like a real traffic light: a tall, narrow silhouette with three 5 mm diffused LEDs stacked vertically. Slide the board into a front panel, stick it on a robot, or mount it on a model-railway street corner then drive each lamp from its own GPIO pin (active-high) just as you would any plain LED.

Arduino Example Snippet 

int ledPins[] = {1, 14, 41};
int numLeds = 3;

void setup() {
  for (int i = 0; i < numLeds; i++) {
    pinMode(ledPins[i], OUTPUT);
    digitalWrite(ledPins[i], LOW);
  }
}

void loop() {
  for (int i = 0; i < numLeds; i++) {
    digitalWrite(ledPins[i], HIGH);
    delay(500);
    digitalWrite(ledPins[i], LOW);
    delay(500);
  }
