I have just about completed my first Arduino project using an Arduino Uno board, but is that what I use inside the finished device? I figured I’d keep the Uno for future projects and have something else controlling the finished product. Are you supposed to just keep purchasing the Uno board every project?
I just got it a couple of days ago so I’m not very familiar with any of it. If that is the case do you use the batter for power since I can’t have it connected to my laptop once it’s done.
