[Kirill] wrote in to share his Arduino-based PIC programmer. It is capable of writing to the 18F family of chips, including 18F2XXX and 18F4XXX. We think that’s pretty exciting because this line of ...

💡 Note: Some PIC microcontrollers require 12V on MCLR for high-voltage programming. If this is the case, you might need an external 12V circuit.

It is recommended to isolate programmer from battery circuit. I did not do any intense research in that manner but for safety i have utilized 220ohm resistors at clock and data lines. "Test PIC" will ...

I’ve always appreciated simulation tools. Sure, there’s no substitute for actually building a circuit but it sure is handy if you can fix a lot of easy problems before you start soldering and making ...
