Title: battery charging circuit for arduino
Post by: dmehling on July 22, 2012, 11:36:39 AM

I am thinking about getting an Arduino microcontroller (not sure which one yet).  For my project, I would like to be able to leave the battery connected to the microcontroller and still be able to charge it.  I saw a post on this forum http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1200471261/all (http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1200471261/all) about using the max1555 to do just that.  However, I am quite a novice when it comes to electronics and so I have no idea how to set this thing up with that particular IC.

Easy enough, just implement the charge controller in the Arduino (with a few discrete components to handle the current), rather than adding a charge controller.
