This is just enhancement to my current code, which monitor the water level, if water fall below the sensor it will turn on the pump.
Right now every six seconds it read the sensor value, if LOW turn on the pump (yellow LED on), after six seconds if HIGH turn off the pump (green LED on). So at startup it will wait six seconds before anything happens, after six second one of the LED turn on (either pump on or pump off state). I wanted to take that only intial six seconds and have the all LEDs to flash before one of the LED remain solid on.
