Hi,
I have tried building a sound trigger referring to the instructions on the HiViz website.
I am having a couple of problems with sensitivity. When using a 100k resistor as they ask for it just didn't work so I started reducing the resistance and have found that a 470ohm works better for me, I can actually get a flash
My current setup is as attached (couldn't work out how to get the pic to display)
My problem is, even though I can get a flash, its not very sensitive, I have to clap really hard to make it happen. Why does mine behave so differently to theirs, could it be the piezo being different? Also, by dropping the resistance, will my battery drain faster?
I am very new to electronics, this is the first thing I have ever built so any advice on how to make it work better would be much appreciated![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
