triac disco light

You can connect the port I/O by optodiac to the triac.

yes you can


you need to decode to parallel data your sending
and use this to gate a triac array


if you type into google search strings like

light sequencer projects
or light chasser projects or addd also the work programmable
youll have much sucess in finding exactly what you need
as free ware apps some cpu controlled by rs232 etc also

this is easy to do anyway

using a simple pic16F 84 and some code and triacs and driver transistors to switch the triacs
{although this wont easily give you a brigness per bulb}

however if you use trick of the eye

and multiplex the output
using a matrix


1 2 3 4

----------------|
the B = ---bulb

you can do this simple project by

driving some i/o on the B port of the micro pic 84

and use port A to talk to computer

using rs 232
choose a sutible baud rate 0 - 115Kbps
with 9600 a usuall rate for good support this type of project

use pic basic pro or another basic pic assebler

free ones are good like picbasic lite,,,,,

and may spur you on to buy or find the full version....

but in looking at it it has enough to do this in way of assembler features

and also a good simple cheep supported and working solution {also legal} use simple com 2 connection {or com1 9600 1 stp 1 strt 0 parity 8 bit word }
