I’m trying to find some information on how to change the speed of my arduino, and I haven’t had any luck. Is there a page or forum posting that’s discussed this before?
I assume that swapping out the crystal/resonator would just work, but that all the arduino timing functions would be wrong (millis, PWM, etc). I remember reading about how to make the changes and reburning the bootloader(?), but I cannot seem to find this info now.
While I’m on the topic:
What is the minimum speed acceptable?
What are pro’s & con’s of a crystal vs. a resonator?
I want to do this to obtain maximum battery life for projects that don’t require speed.
