How do I get my sound detectors to give constant voltage readings on the ADC Graph? I am using the two detectors to see where the loudest signal came from then move the robot's head toward the loudest.
I have read all I can find on Synthiam including the Community and Tutorials but can not see anything that will solve my problem.
The problem is I can't get a consistent signal from in the ADC Graph. The line graph will jump up and down even with the a constant audio signal coming from my sound generator. Since their is no sound consistency I can't write script to make the head move.
Is my problem having to do with the wrong sound detectors or the way the information is handled by the Ez-Robot program?

Hi. Richard gave me the script that would help me make the sound sensor work.
Here is the script:
:loop $left=GetADC(adc0) $middle=GetADC(adc1) $right=GetADC(adc2)
if ($left>$middle)
if ($left>$right) servo(D0,1) // left is highest sleep(2000) goto(loop) endif
endif
if ($middle>$right) servo(D0,90) // middle is highest ELSE servo(D0,180 // right is the highest endif
sleep(2000) goto(loop)
I would like to understand this script. Where can I go to understand the format of the loop script. I have been looking on Synthiam to understand loop but to no avail. I know it loops scripts but I do not understand all the loops and their inset protocol . I really want to write my own scrips using the loop script but right now I do not understand it and don't know how to find how to use it. Please Help.
Thanks for ideas and help.
I am still trying to use Richards script to make my robot Max turn his head toward who is talking. Richards script helped me a lot. I still cannot get it to work but I am working on it.

Above is a my YouTube video that will show you that the three sensors are not peak coordinated therefor I cannot compare voltages at the instance sound is made. I also added a steady tone of 1141 Hz, from my Tone Generator which should show a steady tone on the three Read ADC gauges. If I could get a steady tone on my gauges, I could balance the gauges using the sensitivity on each sound detector. Sensors are Sound Detectors by RobotDyn. I could then use the steady tone from my Tone Generator to balance them.
Here is a pictures of my setup.
Thanks for all the help. Please give me some direction to go.
