Arduino using limits.

Hello,

I would like to know if arduino has any kind of limit about how much can i "charge" it.
I mean, basically how much things i can make works on it. It just provides 5 volts, can i use them to power up
a whole big thing or it has some limits? Overcharge, overworking, etc..?

Thanks! :slight_smile: :slight_smile:

Yes there is limit to how much current you can draw from an arduino board in total. If powered by the USB cable the limit is 500ma, if powered from the external connector a little more can be used but that can be dependent on the amount of voltage the external power source is. Best to keep all projects using 500ma or less, unless you are willing to use external voltage sources independent of the on-board +5vdc regulator or the USB power.

Hi,

Right, thanks I'll take that in mind. Arduino Uno, I'm using, i heard it does not gets damaged by acidentally shortcircuit it for a moment.
Is this true? What if it accidentally gets shortcircuited for kind of long time?
And overcharging in working with arduino may damage or burn it?

If you think you are going to be pushing limits like that, either intentionally or by accident, you might consider an Arduino compatible system that is better protected than an official Arduino. One that I'm aware of is the Ruggeduino. At present, I don't have any direct experience with it: http://ruggedcircuits.com/html/ruggeduino.html.

The creators of the Ruggeduino have a list of 10 things that can destroy a regular Arduno: 10 Ways to Destroy an Arduino — Rugged CircuitsRugged Industrial Arduino Microcontrollers.

Great!!

That was all i needed thanks!
