hello

i want to store five var from 5 sensors .

i want to execute the following program if
sensor 1 = 1000
sensor 2 = 1200
sensor 3 = 1500
sensor 4 = 4000
sensor 5 = 5750

i need help

merci

You store values, not variables.

Do you want to store 5 values from each of 5 sensors? Or one value from each of 5 sensors?

What kind of sensors? Connected to which pins? Store the data where? Persistent over resets?

i want to execute the following program

There is no "following program", and it seems unlikely that you will get a reading of 4000 or 5750 from any sensor you connect to the Arduino.

hello thanks for your answer

i want to compare fréquency from D0

if first frequency from d0 is 1200 and the others (from d0) are 1200 then 1500 then 4000 and then 5750 ,
i turn on a LED

thanks

if first frequency from d0 is 1200 and the others (from d0)

I might be missing something here, but it appears that you want to connect 5 things to one pin, and somehow guess which one you are reading from at any point in time.

D0 is input than receive audio signal

in the same input i want to detect 5 frequency .

if the 5 five frequency are in this sequence : 1000Hz 1200Hz 1500Hz 4000Hz 5750Hz , I turn on the led

thanks

sorry for my english

D0 is input than receive audio signal

Reading an audio frequency on a digital pin doesn't make sense. Even if it did, you don't get frequency from one reading. So, you can't compare 5 consecutive readings, to see if you got that collection of values.

sorry , the input is A0.

thanks

kaiss:
sorry , the input is A0.

thanks

Well, that's better. You still need to take a bunch of readings, to find two subsequent peaks so you can measure the frequency.

What is supplying the signal being measured? How long does each signal stay at a given frequency?

each signal stay 100ms , i can measure the frequencies, it is not a probleme for me .

i don t know how i can do to write this condition :
i want to turn on a led if these frequency are in this order .

thanks

So, you know freq[0], freq[1], freq[2], freq[3], and freq[4]. But you can't figure out how to compare that array to some other array in memory?

Perhaps memcmp() would be useful.
