I want my invention to display the level of sensory input in my environment. To design sure each input bit is sensitive enough but not too sensitive, I hold tested each input alone with just power and the Bargraph. The Light Sensor works just fine.
However, or when I try the same thing with the Sound Trigger,adjusting the sensitivity through trial and error, either all 5 lights on the Bargraph approach on (although the sounds I'm trying are relatively quiet) or the Bargraph does not respond at all.
Has anyone else experienced this problem with the Sound Trigger's sensitivity when used with a Bargraph? Any suggestions? Posts: 5Participants: 2Read full topic
