About the title: I needed to shorten the original to Electronics Interfacing 101, a.k.a. Tips & Tricks
About this Sticky Thread:
Certain questions keep coming back, for years and years. And although many fellow freaks are willing to help, it is a bit of a waste to tell the same things over and over again.
Therefor: A sticky thread that will hold a collection of tips and tricks.
It all started here:https://www.avrfreaks.net/index.php?name=PNphpBB2&file=viewtopic&p=611541#611541
In order to keep this Sticky well-organized, I will moderate this thread extensively: one subject per post. Don't ask questions here, but start a normal thread, and refer (if necessary) to a single subject or post in this thread. See attached snapshot how to get that specific URL.
If you wish to contribute you can post in this thread and refer (if necessary) to the single subject or post as explained above. The moderators of this forum will do the cut and paste actions.
This first post will be used to hold general information on this Sticky, and hold a list of available subjects.
* Interfacing between devices with different logic levels
* About PSU (PowerSupplyUnit) design
* About crystals
Many thanks to all contributors :!:
