@mtiberia.

Thanks for getting back to me and for explaining. So basically, the higher I set the multipucation values, the more sound the sensors pick up on, and setting these values at say 300 would start picking up more background noise. Gotcha.

Just courious, have you ever tried these sensors at 5v? I just wonder what the difference would be. I'm waiting on a delivery for some 5v regulators so I've been unable to test it.

Your not really increasing the sensitivity of the sound sensor. Your using software to accentuate the difference. Just easier to visualize and write conditional statements.

Righty: Lefty:

1 x50=50 1.750=80 # first time through the loop 1.150=55 1.250=60 # second time through the loop

The difference between Righty 1+1.1=2.2 and Righty 50+55=105

The difference between Lefty 1.7+1.2=2.9 and Lefty 50+55=140

I have it now. Thanks again. I'm greatfull for your help.

@mtiberia Is right... You can just use the straight analog values for simplicity (1 - 255)... The higher the value is the side that heard the loudest noise....

@Richard.

Okay, that's cool and a little easier. Thanks for confirming.

@Steve G

I saw your newest video on youtube! your sound sensor is working fine! can you help me with the script ?

I have only one sound sensor from the Robonova Humanoid (picture) my projects: the robot responds to clapping

I use ADC 0

No problem Smarty.

I think this might be the one you're referring too...

:loop
#Read's the value on EZ-B port A0
$sound=getADC(adc0) 

#Will turn LED on when sensor reading is above 5.
#Change the values if necessary.
if($sound>5)
set(d0,On)

#Will turn LED off when sensor reading is below 4.
elseif($sound<4)
set(d0,Off)
endif
goto(loop)

This was the example I used in my ADC tutorial. Click the link below and have a look. Hope it helps.

thanks for your help :-) I think, I have a wrong sound sensor.. I get no responce If I make sounds..

I have a similar like you first one.. now you bought new ones?!

What should I look for when I buy new ones ?
