if not then just use the hex file for programming.

I can supply a kit if you wish with all the parts you need?
Thanks for that
I have no idea about jal so I will just use the hex I think.

And a note for future project: On the 16f628a, port B features internal pull up resistors that are software selectable. You could have omitted the 10k resistors when using A as output and B as input port.
Its mixed to give a nice white colour not the cold white but a warmer white :-)

Ah okay.. but wouldn't it make more sense to limit green and blue output by the software? That way you can easily alter it to give maximum brightness and such without any rewiring.

Im not that sort of person- Im a hardware welding beating metal with a hammer kind of guy lol.

Software editing is too elegant for me so I used the resistor approach....

The 3 mottos I work by are:
"If at first you dont succeed use a bigger hammer"
"if its worth doing its worth overdoing"
"If it doesnt work add something big and heavy"

;D
