You add one of these. https://www.sparkfun.com/products/10228
32  Using Arduino / General Electronics / Re: Voltage divider on: July 16, 2014, 07:08:32 pm
The smaller the resistors the more then current draw.
Suggest you use 4.7K each.
What are you using the voltage for?

Add an alarm to your design.

37  Using Arduino / LEDs and Multiplexing / Re: Multiple leds set; diff pins diff times, initial power up huge 13 brightness ... on: July 16, 2014, 06:38:23 pm
You have to make the pin(s) outputs if you want to control them.
See pinMode
38  Using Arduino / Programming Questions / Re: Using a short to prevent program form running on: July 16, 2014, 06:27:04 pm
You could do this in setup() , check the pin if it is High then check it again. When it goes Low the allow the code to proceed in usual way.

Lastly, I need to have a timeout if no pulses are received to indicate 0 frequency
You chould easily add code to do this. Start a timer if no change for X milliseconds trigger time out code.

Here is some code you can use/modify to your needs.

For long sleeps.
https://code.google.com/p/narcoleptic/

Code:
void longSleep(long milliseconds)
{
    while(milliseconds > 0)
  {
       if(milliseconds > 8000)
      {
             milliseconds -= 8000; Narcoleptic.delay(8000);
      }
       else
      {
         Narcoleptic.delay(milliseconds);
         break;
      }
  }
}

There is no way you will see a difference in a residential home when you try to adjust PF.
44  Using Arduino / Project Guidance / Re: Guide on Arduino Uno on: July 15, 2014, 12:09:59 am
Fake it:
Just use the Arduino analog input and a known resistor with the resistor of interest, calculate the unknown value.
45  Using Arduino / Microcontrollers / Re: New 1284P format - 1284OnTop, Bobweeny? on: July 13, 2014, 12:04:10 am
I like the dip format, burn it up throw it away, plug a new 1284 on the PCB.
