AtoD - first attempts

Yeah I 'spose when you think of it I would need to rectify the AC signal in some way so that there is something for the pic to read.

I'll try the diode / capacitor thing and see what happens.. thanks for the input

Oh it works pretty good, once you get the caps/resistors all set up to the right numbers. I don't remember the values that I used, but I do know I ended up buffering the input with an opamp before going into the diode. I've got a decent pdf of what I did around somewhere. If I find it, I'll link it.

Hello Skimask / Malc-c,

I also want to pursue this project and was wondering, what was the overall results of Malc-c project.

In abscence of some design guidelines (Schematic) from Malc-c side towards the project, I would like to share my idea.
1. I also wish to make a dancing light controller with musical input on a ADC port or a PIC 16F72 / 16F873A to make PORTB dance to the music. REALTIME
2. I am also interested in digitizing the pattern of the music , so that it could be replayed without any music source. STORE/PLAY

I would first like to work upon the REALTIME idea and then jump over to the STORE/PLAY version.

Could anyone please guide me thru this.

regards

p.s. Wonder it this thread is still alive
