I am working on a project with a SEN-12642 sound detector, but it is not working. The light will respond to sound, but data points do not change accordingly. To try to see changes more clearly, we tried both squaring and multiplying the data output, which gave us numbers in the -1000s instead of the 200s it had been in. We have also tried to use a resistor to increase the sensitivity by adding a 1M ohm resistor to R17 and removing R13 as stated in the manual. Having both R13 and R17 gave the same data. What might be the cause of issues I am having and how do I fix it?
