I don't know if this has been posted anywhere else, but I did a search on the forums for the link and didn't find anything.

 

This is a web page outlining the 10 easiest ways to blow up your Arduino, and how to protect against this. It also covers some info on just the ATmega328p on the Arduinos. Great info for a beginner Arduino user.

I remember seeing Ruggeduino being posted here before.

By far the simplest way not to harm the Arduino is to simply leave it in the box, correct?

If you want instant feedback on the result... a 10lb hammer also works a treat.

But to not see the smoke and feel the heat given off by the device as it struggles to live, one would be remiss.

Good to read, thread is valid for all AVRs, including my /almost dead/ one.

 

How? A clever socketed AVR design, one tantalum cap was soldered under, but wrong oriented.

There was not any smoke /not yet/ but a lot of funny smell, and AVR was heated a lot, together with 7805.

Why do those tantalum caps miss the Plus mark, I do not know, I learned a lesson.

Like this:

 

here is a secret of Plus:

Just to note that the problem with Tutorials that simply contain a link to an external site is that too often we find that after a year or two the external site disappears for some reason. Far better are tutorials with the info in #1 or at least something like a PDF copy of the info so it will remain after the site dies.

 

EDIT: I have attached a PDF but I'm a bit wary about it as it now raises the question of copyright surprise

Of course it's not a good thing to do, but would shorting IO pins together actually blow anything up?

 

You'd have the resistance of two drivers in series - would that be enough to limit the current?

 

(a bit like people get away with connecting LEDs to port pins without series resistors)

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected
  4. Difference between a crystal, and a crystal oscillatorhttps://www.avrfreaks.net/comment...

I hear you Cliff, didn't think of that, thanks. As you say though, I don't know the legal implications of quoting the actual page here.
