thanks now how to determine input
level (output of the PIC18F1320??
5v supply with a 10k resistor on the output = .0005ma
how large of a resistor to use to get more volume BUT the speaker is only .3w
I have currently 2 speakers from Mouser
665-AS02808MR2R sounds ok but more volume. currenty running using just a 2n2222. sounds just like when I connected the LM386
665-AT-1620-TWTR have yet to try out
