Triac on PIC Output hardware help - Electronic Circuits Projects Diagrams Free

Hi I want to confirm about this circuit. I’m not sure about the TRIACS M1 connects to the correct place?
Any adjustments do I have to do?

Please don't' tell to use an opto isolator here no place to buy them I have only BT136 triacs.

BANG!!! - what's that zener doing where it is?

The above method is working(i mean 4.5V is coming). what about the M1 terminal does it need to connect to Neutral?So VSS & Neutral connecting both?

If it's working then what's labelled as a transformer can't really be that, or it's going to die (along with the zener) fairly shortly.

How have you 'invented' such a non-workable circuit?, you've certainly never seen anything wired like that!.

I mean its not working but the 4.5V is coming to the PIC.

But still I'm confused with that M1 terminal.Don't know where to fix.

It obviously has to go to the neutral, but don't leave the zener wired like that, it's WRONG and something is going to die because of it - wire it properly.
