I am a newbie to Arduino, so please bear with me. I am trying to figure out how to power an Arduino Nano with a LiPo battery. I want to use a 3.7v if possible, as my project needs to be lightweight. There are two possibilities I know could work:
-Taking a USB to Mini-B USB, cutting off the normal USB end, and soldering a connector (based on the battery I use) to that end. I would then plug the Mini-B USB into the Nano, giving it power.
-Using the 5v and Ground pins.
I would prefer to use the USB cable solution, however the 5v/Ground or any other solution is perfectly usable.
Also, would 3.7v be enough to power the Nano, two Infrared LEDS (Launch and Receiver), and a 7-segment LED display. I also have a button. Thanks, saddlepiggy!
