i have the arduino starter kit. the codes that came with the arduino come up with the same thing. here is my project. The IDE is 1.6.11
int switchState = 0;
void setup() {
pinMode(3, OUTPUT);
pinMode(4, OUTPUT);
pinMode(5, OUTPUT);
pinMode(2, INPUT);
}
void loop() {
int swichState = digitalRead(2);
// comment
if (switchState == LOW) {
// the butten is not pressed
digitalWrite(3, HIGH); // yellow led
digitalWrite(4, LOW); // red led
digitalWrite(5, LOW); // blue led
}
else { // the button is pressed
digitalWrite(3, LOW); // yellow led
digitalWrite(4, LOW); // red led
digitalWrite(5, HIGH); // blue led
delay(250); // wait for a quarter second
// toggle the leds
digitalWrite(4, HIGH); // yellow led
digitalWrite(5, LOW); // red led
delay(250); // wait for a quarter second
}
} // go back to the begining of the loop
