I was wondering if for a project like my bluetooth lights( where all it is is a BlueSMIRF UART and digital outputs to LEDs) would need a voltage regulator
I mean can't I just use a 6V battery and not need a regulator , b/c I am not using any ADC . The digital outputs I know would be fine, but would it affect the UART?
I have found with my PIC microcontrollers that an unregulated power source didn't make a difference when no ADC was used. I'm just not sure about AVR.
Thanks,
Eric
