Sorry for the possibly repeated question.....
I want the cheapest PIC that has internal clock good to 5% , input  
from switch, output to triac and output to 20 ma bi-color LED.
Should the LED be buffered ?
I want to run this off 220VAC / 110VAC as cheeeeeply as possible.
Should I use a resistor and zener ?

Unit will have PIC, one pushbutton, one triac, one bi-color LED, AC  
plug and socket.  It will be an inline power switch ( on/off only )

Best
Gus
