Hello all,   noobie going through tutorials > actually all is going well > except:example in basic navigation >  forward Stop Face Right.side = program does what it's supposed to, except when I put it on the floor in pos #2 it keeps going over & over 
Question: 1.Why does the program execute more than once? did it somehow get loaded to eeprom multiple times? (reset doesn't seem t matter)
2. been looking at post on 'clearing eeprom' but eeprom is over-written each time you upload to eeprom isn't it? ...so,it shouldn't need clearing then, right?
Thanks in advance for any help....

You're right about the EEPROM being overwritten each time  you load to EEPROM.
If you add a link to the exact tutorial you're working on, it would be easier to know how to help.

Using my robot (calibrated, full batteries) I could not repeat the behaviour you are experiencing. The first thing that comes to mind, though, is that perhaps your batteries are old/low and the board is resetting. This would cause the program to re-initiate each time it reset.

Please put in 5 fresh AA batteries and see if this resolves the issue.

Thanks Both, 
Duane: I thought I read somewhere that there was no need to clear eeprom - thanks for confirmsorry, I'll post links form now on:  http://learn.parallax.com/activitybot/set-certain-speeds

Courtney: spot on - solved: - thanks for one of those 'can't learn in a book' pieces of advise - erratic behaviour (board reset) = check batteries - lol!

Don't worry. We have all been there, even when we "know" the batteries are good.
Carry on with the tutorials. !

Learning that behaviour early on is really helpful, I'm glad you got a chance to see it.

Have fun with the ActivityBot tutorials; we'll be here if you need advice or help.
