Hello, I’m setting up a program to display temperature to a LCD, compare the displayed temperature to a value set by a pot, then turn a digital I/O OFF or ON depending on temperature… temperature controller for a laminator.
My question, is there any reason to use a 16mhz crystal vs a 16 mhz resonator on a board for this controller? I have developed the sketch on the Arduino m168 chip, but will etch a PCB for the circuit. a resonator is a tad less expensive than a crystal.
Thanks to all for any help and suggestions.
