As the title suggests, I am starting to take the first steps to develop some battery-powered nodes, and I started with some work already done found here on the forum.
I have some Atmel 328P barebones on which following this:
procedure and with an arduino Uno and Arduino IDE, I managed to burn an 8Mhz Bootloader with internal oscillator, and to load a simple scketch of a motion sensor, which should work on battery power, and during sleep, it has an absorption of 0 , 19mA (maybe a little high ???).
At this point reading this discussion: link text
it reads that I should set the fuses in order to disable the BOD, which if I understand correctly serves to make my circuit work even with lower voltages !!
Someone tells me the precise setting that I have to give, so I modify my fuses with AVRDUDESS ???
Then another thing, when I connect the serial monitor through my arduino Uno that I use to load the sketches I get this Why ???
