Using an Arduino. Modify our original traffic light to have 2 sides, and let the user enter the time (in seconds for each color [red, yellow, green]

We want the user delay to override the delay I have given as default value permanently.

I use a MEGA 2560 Arduino.

This is my origonal code.

int ledDelay = 2000; int redPin = 10; int yellowPin = 9; int greenPin = 8;

void setup() { pinMode(redPin, OUTPUT); pinMode(yellowPin, OUTPUT); pinMode(greenPin, OUTPUT); }

void loop() { // turn red on digitalWrite(redPin, HIGH); delay(ledDelay);

digitalWrite(redPin, LOW); digitalWrite(yellowPin, HIGH); delay(ledDelay);

digitalWrite(greenPin, HIGH); digitalWrite(yellowPin, LOW); delay(ledDelay);

digitalWrite(yellowPin, HIGH); digitalWrite(greenPin, LOW); delay(ledDelay);

digitalWrite(yellowPin, LOW);

}
