Would anyone share a Fritz of a project that exceed the arduinos 5v power?

Hi Guys,

I’m struggling with figuring out how to create a fritz model of an arduino project that exceeds the power supplied by a single arduino.

I figured I would use either SSR’s or relays controlled by the arduino to send power where it needs to go. For whatever reason, I’ve just never been able to grasp how to get the power to the sensors, motors, servos or what have you.

Here’s what I’m interested in doing.

I have a 2700mAh Rechargeable Lipo Battery that’s rated at 11.1v. I have a computer fan that’s a 12v DC fan. A relay controlled by the arduino would control the fan turning on and off. I think the best thing for me is to see the layout because I’m much more of a visual learner and my reading comprehension sucks…so if anyone has a fritz of any project that they could share that I could poke around in, it’d be very helpful.

TIA!

There are many useful schematics on the Pighixxx website
