Arduino Backup Power Supply at Melina Baker blog

Arduino Backup Power Supply. The simplest way to connect a emergency backup battery as you describe is by diode oring. However, this project is powered by a shared 5v supply from a 230v to 5v psu module. I did a small project with arduino to control and monitor an aquarium. There are a lot of electronics that need to be reliably on all the time. Just like a computer ups (uninterruptible power supply). I want to have a circuit that swaps the power source from ac to dc when ac power is unavailable. I would like to design some kind of pcb that would charge a backup battery from. I have a very simple project that is working off of an external wall wart power supply and i would like to add a back up battery in case of power. Learn to build a battery backup supply for small electronics so you never run out of power. I have powered that from a small 9v dc power supply. Alarm clocks are a good example of this. It has 5000mah battery and 5v 2a output. Both the power supply and the battery dump onto the internal power bus thru a diode.
