I tried and tried but... you lost me in your explanations.
Now i have a input that when made gets the signal and set a alarm setpoint one LED lower than the current signal === First problem with the signal variang fast it does not whant to select properly

Now what needs to happen is that as soon as the signal passes the setpoint again it needs to set a output basicly a high noise alarm, but my rele shutter if i add a timer it influence my VU meter
