Hi,
I have a program where once you press a button, I want the arduino to wait 3 seconds before starting 2 LEDs flickering. After another 3 seconds I wish to send another pin HIGH (and still have the LEDs flickering).
My problem is that the LEDs take longer than 3 seconds to start flickering, and come on at the same time as the final pin is sent HIGH.
My code:
int buttonPin = 2;
int ledPin1 = 11;
int ledPin2 = 10;
int elPin = 7;
int buttonState = 0;
int ledState = 0;
void setup() {
pinMode(ledPin1, OUTPUT);
pinMode(ledPin2, OUTPUT);
pinMode(buttonPin, INPUT);
pinMode(elPin, OUTPUT);
Serial.begin(9600); // set up Serial library at 9600 bps
}
void loop() {
buttonState = digitalRead(buttonPin);
if(buttonState == HIGH) {
delay(3000); // Starting delay
ledState = 1;
delay(3000); // Delay before el wire
digitalWrite(elPin, HIGH); // set the EL Wire on
}
if(ledState == 1) {
analogWrite(ledPin1, random(200)+55);
analogWrite(ledPin2, random(200)+55);
delay(random(50));
}
}
Thanks for your help!
