I am planning a project very similar to the one seen in the following gallery. (http://imgur.com/a/G7iww) I like the idea of having my phone plugged into the same unit for charging. My only concern is I only want to have one power cable being attached. The power cable needs to power both an Arduino Micro, some LEDs, and charge the phone, so I will likely be using a 5V wall wart or something similar (high enough power rating).
My big concern is making sure the battery is charged properly and is not over charged. I don't want to just plug it into a constant 5V-1A circuit, and ruin the battery. I have seen a few charging circuits online (like this one), but did not know if this was a safe option.
Any suggestions would be greatly appreciated. I am looking for a package that is relatively easy to use/solder and is reliable/safe. There are plenty of charging circuits, but are not exactly user friendly for small-ish hobby projects.
For what its worth, it is an iPhone 6 that needs to be charged, so it is a 3.8V 1800mAh lithium ion battery.
