blink light

[Andrea Becagli]

I have flood sensor witch sends me an alarm in case of flood. When the alarm state is triggered i need to make a light blink constantly until the alarm stops. 


I created an event-based script triggered by the state of the sensor and inside I created a while loop inside:

Code:

while grp.getvalue("stato sensore") do
  grp.write("luce", true)
  os.sleep(1)
  grp.write("luce", false)
  os.sleep(1)
end

Now it works but it easily overloads the CPU pretty easily. Is there a better way to do this?
