I basically want to light "everything" in as many patterns as possible: light chasers, all 16 at time, blinking, fading (maybe if I use PWM), rotating, etc, etc. I want individual control over 110...

It's been a while since I was here 'cause I was really into getting the Arduino/AC matrix going. AC matrix with triacs or SSRs does not work. The matrix part works but there is too much leakage...

I made a model, using mono-color LED, and I2C port expanders. Worked extremely well.
I then made a model using RGB LEDs, again with port expanders and wired in a matrix so I could turn on just the...

Attached is my proposal. One PIC driving 7 MCP23017 port expanders, driving 6-16 channel triac boards in a matrix (the seventh board is the matrix controller that controls what segment gets turned...

My wife also does 1/12 scale "dollhouses" and has about 20 different scenes. And I light some of her work as well. Wife has won a number of competitions and has been published 1/2 dozen times.

Thanks for the reply. I've done more research, looked at Arduino examples (I have lots of Arduino, but PIC seems better because of the great IDE and PBP!)
The PIC will be talking directly to the...

I did a project where I used a PIC 16F887 and used all the ports, A,B,C, D for outputs to triac boards. Lots of wires.

Now I want to do another similar project using I2C protocol, conversing with...
