The function delay pauses the program for the amount of time (in milliseconds) specified as parameter. This can make your project a bit confusing sometimes, especially when you use it in Processing. As an advice, never use delay function in Processing.
Below a sample code you can use in Arduino:
int period = 5000; long time_now = 0; void setup() { Serial.begin(9600); } void loop() { if(millis() >= time_now + period){ time_now += period; Serial.println("Hello"); } //Run other code }
If you are using Processing the code will be this:
int period = 5000; long time_now = 0; void setup() { } void draw() { if(millis() >= time_now + period){ time_now += period; println("Hello"); } //Run other code }
