 Bigger Bigger  Smaller Smaller  Reset Reset

Hello!

I'm new in the arduino world, at first I was wondering what is the maximum amperage that my arduino uno can resist if nothing is connected on pins

I want to control a 10meters led string rgb, which works with 6ampers and 9volts, can i do it directly or should i use a transistor?

Thanks to all

You should use external power supply which can handle 6 Ampere and Power MOSFET or Transistor with Arduino's PIN.

9V is rather odd for an LED strip, is this some hacked xmas-tree lights?  12V is
more common for strips and easier to find a power supply for (in the 6A range).

There are examples of how to control high current loads in the playground I believe.
