making music using PIC :D

[Transistorman]

i just got an idea to make a music
using PIC , to make it work i find
a shine wave circuit which it use a series of resistor
**broken link removed**
every time a resistor hit other resistor it will make a
different sound
but i didnt not really understand how to programming
the PIC , im still developing the program but i have some
question .
how to moving the high output
from pin to pin
without delay but every time the pin is high it
will play within 0.5 second
, i following some blinking led script and changing some code
but i still dont understand about this
because to blinking led its only use one pin
but the shine wave uses many pin
,
if anyone could help me on this project
it would be helpful

There is a free BASIC out there that does just that, called Studio. You use it with an inexpensive ($8) PIC called the Nano. This can be seen at
Basic ATOM Nano 18
The USB programmer for this is another $15. That's just $23 for both.
The command to make music with eight "voices" is "SOUND8", and looks like

Example
dur1 con 2
dur2 con 1
nA con 440
nB con 494
nC con 523
nD con 587
nE con 659
nF con 698
nG con 784
nA2 con 880
sound8 outl,[dur1\nc\ne\ng,dur2\nf\na\nc\a2]
This program first defines nA – nA2 as the musical notes (equal tempered scale) A, B, C… A2 respectively. Then it plays the chord C-E-G for 2 seconds (on pins P0 to P2), followed by the chord F-A-C-A2 for one second (on pins P0 to P3). The remaining pins on the port remain silent. Of course, flats and sharps can also be defined; a quick internet search will give you the frequencies you need.

Pretty simple, huh?
A quick schematic for the summing circuit, and there you have it!

thanks for the reply
i still developing the program
: i thinks its too expensive

You can use picbasic pro and make sound easy It's free for 50 lines of code you can do a lot in 50 lines
here a sample from them

        Include "bs1defs.bas"           ' Include BS1 variables

SND     con     0                       ' Define speaker pin

loop:   Random W0                       ' Randomize W0
        B2 = (B0 & 31) + 64             ' Generate notes [64..95]
        If B2 >= 68 Then beep           ' Make [64..68] silence
	B2 = 0
beep:   Sound SND,[B2,4]                ' Generate sound
        Goto loop                       ' Forever

And you don't need a ton of resistor just a cap and a small speaker you can hear it with that If you need louder any cheap
computer speaker amp will do. You can find a cheapo that uses just 2 battery's

hi thanks for the for the post
i will try to downloading PicBasic
my internet is to slow for now

Whyyyyy does no one talk about great cow basic here?!!
it's an open source basic compiler!
