Thanks a lot guys
for helping me choose my uC.
yes!!! I chose PIC16F628.
I found it easily and it cost just Rs130 (USD2.6). thats wow!!!
considering what it can do.
The next issue now is to build a programmer for it. But there
are so many designs on the net :shock: from the one that
connects the chip directly to the parallel port to the USB ones capable of programming the whole PIC family and ICSP etc.
I am confused which one I should build. I guess the simplest one is not safe enough for the computer so I am inclined towards the next simpler one like the one shown at

But wondering If it will work with PIC16F628 without any changes
and if I can replace the 7405 with 7407 with no other changes.
