The project illustrates how it managed to power AVR microcontroller from a single AA battery with simple circuitry which is also driven by the AVR microcontroller.
The Arduino based capacity tester of true battery power is capable of measuring almost any type of rechargeable or non-rechargeable batteries by fully discharging the battery with known current and log data to PC.
Almost all devices like mobile phones or iPods can be charged by this tiny USB battery charger through USB and by using only two AA cells.
The project aims to create a charger for lithium ion batteries which takes its power from the USB port of a computer.
The project illustrates a universal charger for Li-Ion battery using a Smart Battery interface based on Atmel ATmega8 microcontroller with GCC software.
The project produces a battery charger that may be used to charge NiMH, Li-Ion, NiCad, sealed lead acid, and rechargeable alkaline batteries.
