I am new to this forum, so if this topic does not belong to the right place of the Arduino forum, please admin move it to the right place.
Right now, I am currently working on a project on my university, where we are going to build a LED cube with 5x5x5 = 125 LEDS.
The processor we are going to use is an Arduino MEGA 2560. We are going to use 8000 mcd blue LEDS that will light up and make some cool effects.
In order to make this project more practical, we have decided to use a toggle switch to turn the Arduino processor on/off, so that the LED cube can be switched on/off.
We have been looking to this type of toggle switch:http://www.kjell.com/sortiment/el/elektronik/elektromekanik/strombrytare/vippomkopplare/vippstrombrytare-1-pol-on-on-p36127
But this toggle switch is handling 12 V/25 A as it says. Since the Arduino processor can only handle 5 V, how would it be possible to connect the toggle switch to the Arduino processor?
Here is how the schematic of the Arduino MEGA 250 should be looking like.
