How to develop labview program to control 4 LEDs base on different frequency range.

[Bioengineer_UM]

 Hi there,

I have a project to develop Labview program to control 4 LEDs base on different sound freqency range and i have to use DAQ as an interface.

for example,

1- when the sound is low one led will on and the rest will be off , 

2- then if i increase the sound two leds should be on and the other two will be off.

3 -higher sound 3 leds on and on off

4- highest sound all 4 leds should be on.

well, if it is  differcult to differentiate sound level we can use other input but it fulfill that it should have 4 levels so we can get there requied sequences

Sohowdo Imakeitwork? 

thanks in advance.

YOu can find links to Dr. Damien's Xylophone series here.

Looks like that last one in the list is what you should look at.

thanks Mr. Ben,

 i have created this program(attached) to aquire sound from my PC ( the first block) and the other on to ON and OFF the LEDs.

my problem is that i do not know how to connect them to each other. and i think it needs a case sturcture to control the ON and OFF sequence.

i will be greatful if there is any help.

thanks for you kind help.
