Hi guys im trying to run a traffic light system, but when i compile the code i got an "expected '}' at end of input"

without more to do i'll leave the code.

// Semáforo Arduino 
// define the pins that the buttons and lights are connected to:
#define westButton 3
#define eastButton 13
#define westRed 2
#define westYellow 1
#define westGreen 0
#define eastRed 12
#define eastYellow 11
#define eastGreen 10
#define yellowBlinkTime 500 // 0.5 seconds for yellow light blink
boolean trafficWest = true; // west = true, east = false
int flowTime = 10000; // amount of time to let traffic flow
int changeDelay = 2000; // amount of time between color changes
void setup()
{
// setup digital I/O pins
pinMode(westButton, INPUT);
pinMode(eastButton, INPUT);
pinMode(westRed, OUTPUT);
pinMode(westYellow, OUTPUT);
pinMode(westGreen, OUTPUT);
pinMode(eastRed, OUTPUT);
pinMode(eastYellow, OUTPUT);
pinMode(eastGreen, OUTPUT);

// set initial state for lights - west side is green first
digitalWrite(westRed, LOW);
digitalWrite(westYellow, LOW);
digitalWrite(westGreen, HIGH);
digitalWrite(eastRed, HIGH);
digitalWrite(eastYellow, LOW);
digitalWrite(eastGreen, LOW);
}
void loop()
{
if ( digitalRead(westButton) == HIGH ) // request west>east traffic flow
{
if ( trafficWest != true )
// only continue if traffic flowing in the opposite (east) direction
{
trafficWest = true; // change traffic flow flag to west>east
delay(flowTime); // give time for traffic to flow
digitalWrite(eastGreen, LOW); // change east-facing lights from green
// to yellow to red
digitalWrite(eastYellow, HIGH);
delay(changeDelay);
digitalWrite(eastYellow, LOW);
digitalWrite(eastRed, HIGH);
delay(changeDelay);
for ( int a = 0; a < 5; a++ ) // blink yellow light { digitalWrite(westYellow, LOW); delay(yellowBlinkTime); digitalWrite(westYellow, HIGH); delay(yellowBlinkTime); } digitalWrite(westYellow, LOW); digitalWrite(westRed, LOW); // change west-facing lights from red to green digitalWrite(westGreen, HIGH); } } if ( digitalRead(eastButton) == HIGH ) // request east>west traffic flow
{
if ( trafficWest == true )
// only continue if traffic flow is in the opposite (west) direction
{
trafficWest = false; // change traffic flow flag to east>west
delay(flowTime); // give time for traffic to flow
digitalWrite(westGreen, LOW);
// change west lights from green to yellow to red
digitalWrite(westYellow, HIGH);
delay(changeDelay);
digitalWrite(westYellow, LOW);
digitalWrite(westRed, HIGH);
delay(changeDelay);
for ( int a = 0 ; a < 5 ; a++ ) // blink yellow light
{
digitalWrite(eastYellow, LOW);
delay(yellowBlinkTime);
digitalWrite(eastYellow, HIGH);
delay(yellowBlinkTime);
}
digitalWrite(eastYellow, LOW);
digitalWrite(eastRed, LOW); // change east-facing lights from red to green
digitalWrite(eastGreen, HIGH);
}
}
}

I do not need to say that I'm starting to use the program :v

Try Auto Format in the IDE. Where does the loop() function end ?

3

What happens when you format your code by pressing:
CTRL T

.

Yea i got auto format already and still got "expected '}' at end of input".

and for where the loop ends i have no answer for that lol.

6

and for where the loop ends i have no answer for that lol.

A clue. After Auto Format the last line of code in the program should start on the left margin of the editor and the last character in that line (comments aside) should be a closing curly bracket which marks the end of the last function in the program.
