bool ticktock;  //declare ticktock as a boolean flag

void setup() {           //runs once on start up
  Serial.begin(115200);  //open the serial port for USB cable
  delay(500);
}

void loop() {            //runs in circles!
  ticktock = !ticktock;  //every pass through reverse the flag
  if (ticktock) {        //test current value of the ticktock flag
    Serial.println("tick");
  } else {  //prints one or the other to the USB port
    Serial.println("tock");
  }
  delay(1000);  //wait for a second and run again!
}

(I'm also not a fan of the codegen done by any visual programming engine, but that gripe is more stylistic than substantive)

I am reasonable at C++ but I really prefer doing prototyping in Python and I like the drag-and-drop UI of the UIFlow2 IDE. I've just been saving it in a text buffer.
