As far as I know neither li-po batteries nor AA size 1.5 volts batteries supply constant voltage (Even not sure if there is any battery type that supply constant voltage).
So, I am working on a project which will be powered by one of those options, either one cell 3.7 volts Li-po battery or 3-4 AA size batteries connected in series.
I need to power an AVR (atmega328p) and a bluetooth module, which require constant voltage.
What is the best option to sustain the same amount of voltage for those ICs ?
