Step 6Build the circuit
Following the schematic posted below and build the circuit.
This will require using a fair amount of circuit board. I used two from Radioshack. On one I put the PIC chip and the 7805 regulator (and a relay I ran out of space for). On the second board I put the relays and the shift register.
I built as much of the circuit as I could and then I added the potentiometers and lastly wired it to the audio circuit.
I didn't wire up things that would need to be installed in the side of the case like the power plug and the volume knob. For testing I temporarily included a 9V battery adapter.

Would it be too much trouble to ask for a little higher resolution picture of the schematic? Thanks!

In a few weeks I will be posting a new project with a much better circuit for doing the sequencing based on a 4017 decade counter.
