 		 #175700 - no, I do not know what your product is
Responding to: ???'s previous message
when we know this can get back on track

is your product
a) an expensive very best non-destructive lamp dimmer
b) a cheap lamp dimmer where one in 1000 may fail every year

1) going to be produced in thousands
2) going to be made a few

x) going to be approved by whatever electric code your country has
y) not x)

               Great Idea !            01/01/70 00:00      
                  But i've used up INT0 and INT1 pins            01/01/70 00:00      
                     int0 is gate for timer0            01/01/70 00:00      
                     T1(T0) pin is not use here            01/01/70 00:00      
                        so only one Ext.int pin will do            01/01/70 00:00
