![]() I'm fine to do a little soldering if that is needed. What I'd really love to see is what parts are needed as well as where the connection of these parts hook into the Nano. I've seen a few diagrams that show powering the servo with its own battery and the Nano with another ? Is there a simple tutorial that show how you can power a Nano with +/- 5v of power so that it can run a Servo and a BMP180 or BMP280 - the BMPs only need 3.3v. I get that I need to provide power either via the mini USB or directly to the board in the form of battery power but all my searches lead me to project about recharging batteries and things that seem to complicate my simple needs. I want to look at moving to using a Nano to streamline the design and I am getting stuck at the powering of the Nano. I think the Uno solution is working just fine and I am powering it with a 9v battery via the simple battery connector. Right now I have a project which is both an Altimeter as well as a Servo Parachute Release for my water rockets. I am a beginner when it comes to Arduino and electronics, but I've built a few projects on an Uno and am having fun with it.
