So I am planning on using the Arduino nano for the brains of my garden watering project. I have a 12 volt power converter I kept from an old set of boot dryers that fell apart years ago. I know that the Nano can handle the volts but seeing as it's at the higher end of the acceptable range and I want to leave this thing plugged in 24/7, I think I'll use one of my 7805's. And since they lower voltage to 5 volts, I assume I can just run the power straight into the 5v pin.
Does this seem like a waste of time?
Also, am I blogging properly? I am so green...:(
