LIGHT CONTROLLER

[eugene2021]

want to build a light controller w/pic chip light controller will be controlled from pc serial port can build board . will use max232 for interface .want to control an american dj RP-8 (this is just 8 ac outlets connected to 8 relays) this will be buffered by uln2803 . want to have pic chip take pc data ( e.g. n1= ch 1 on relay on , f1 = ch1 on relay off) need help writing code fer this pic chip . do not know how to get pic to look at serial port and turn on correct relay

OKAY SCRATCH THE PIC CHIP ,I NOW HAVE A GUY THAT WILL GIVE ME 5 ATMEL CHIPS AT90S2313 TO TRY TO BUILD THIS CONTROLLER.ANYONE HAVE ANY EXPERIANCE W/THIS CHIP?

Go to www.avrfreaks.com and download the free C compiler there.
This should only require a 10 line C program.

found code that will turn on first relay , what routine or code do i use to get this avr to turn on/off the other 7 relays . this is pretty cool stuff
if i just add same code but change ports ,will this work

if you just want to control 8 relays with the seial port, then there is no need to use a microcontroller.
you can do this with a simple shift register.
or you can control directly the 8 relays with the paralel port.

yes if you are gonna control the relays with a PC then no need for a u controller.. check out my thread " pic programming help" .
3/4 down the first page is my schematic, which you could use the Flip Flops to turn the relays on and off with , although my circuit is used on the ISA slot could be used (with some modifications) on the parallel port..
