A diode would be better. Silicon diodes drop the voltage by about 0.7V when it passes through them. Two of them in series would drop it by 1.4V, etc.
Wow, I am really impressed on all the input I got. This goes a long way to helping me learn. Thanks everyone.
The problem with that is you seem to be (or wanting to) learning basic electronics by memorizing a series of 'rules', rather then studying basic electronics DC Lefty

Witch in reality puts out 6.24vdc and makes my scanner blink crazy.
AVRs can work comfortably at 6.24v.
Maximum Operating Voltage ............................................ 6.0V
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent dam- age to the device. This is a stress rating only and functional operation of the device at these or other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
AVRs can work comfortably at 6.24v. If you are really concerned about it, you can put a diode or an led in serial + a resistor to pull down the voltage.
I'm counting at least 4 moderators now that think dhenry be banned for this crap.
