I want to make a low power blinky project using a 328 and batteries. I keep reading about setting fuses. I read somewhere on here (i can't find it now) that all you have to is select an 8mhz board from the arduino drop down list and burn its boot loader. Is this true? It can't be that easy.
I'll assume that then i do not need to use a crystal (or resonator) and that the 328 will run as an arduino on its internal osc.
Will i have to trim up the internal osc to get the boodloader to recognize the serial programming. Or will i have to continue to use the isp.
