well i've found a shematic to have sound in (level) in a BX24, it was looking quite easy to do....( it was a trap)http://www.tigoe.net/pcomp/code/archives/000254.shtml
i've tried to build the circuit but i've got some prob
- i don't find a LM386 but a LM386-3 (datasheet
- i give a +5V from the arduino (i've tested to with a separate power circuit)
- my value from the adcpin (in the shematic) never change (i've shout in the mic :
) alway ~2,5v
i've tried to modified the pot... nothing better.
in fact i'm not an "electronicien"... if i use a LM386-3 and not a LM386.. is it important :-/
what i have to modify...
