i controlled my avr microcontroller and it is working fine for its power supply i used 12 v 1 amp dc adapter and in mid we required power in absense of genral power supply so i used 12 v 7ah smf lead acid battery .
but i m confused is that diagram will work fine.or i need any changes
and regarding fuse i m also confused which fuse ( 1, 1.5 or 2 amp ) ishud use and where i shud place
main thing is when power is continue then i can take power from adapter directoly or if power goes then without any power flicks ican take power from battery and battery can be charged properly through adapter.
so please guide me what i shud do for this
