Help please!!! Ghetto parallel port uc programmer issue!! Answered

Someone please help!!
I have made the ghetto parallel port programmer  from here : https://www.instructables.com/id/Ghetto-Programming%3a-Getting-started-with-AVR-micro/

I am stuck with this problem since a very long time!!

> "make.exe" program
avrdude -p attiny2313 -P lpt1          -c dapa               -E reset  -U flash:w:LED_Demo.hex

avrdude: AVR device not responding
avrdude: initialization failed, rc=-1
         Double check connections and try again, or use -F to override
         this check.

avrdude done.  Thank you.

make.exe: *** [program] Error 1

> Process Exit Code: 2

- That means you made some wiring mistake. Triple check your connections.
- Make sure your Attiny2313 is getting external 5V on its VCC pins to power it up(it took me a while to figure that out when I made my first ghetto programmer).
- Make sure the ground of ghetto programmer, the external 5V supply and the GND of Attiny2313 are connected together. All grounds should be connected together.
- Check the connections, again... :)
