50$ robot (Almost done!!)

I have just programmed my microcontroller and the program said program successful, but I thought the LED was supposed to turn on... If my batteries ran out during the program I have to redo it right?  And by the way, Admin, I used the dongle programmer and it took less than a minute to program... I would have to guess it would be the serial to usb connection that slowed you up...

do a search on the forums, this question has been asked several times already

Ok, another problem that I'm pretty sure I know the answer to but feel that I should ask... When I modified my servos, I turned the pot until the gears stopped moving and them glued them in place, but after the glue dried, both servos were slightly off (they still rotated when told to go 0)... All this means is my servo speeds will be off right?

Airman00:

its fine the way you did it


now you'll have to experiment to find how much off you are from the pulse

For example : its supposed to be 150 ( lets say) and now on your servo its 156. Play around to find the pulses for forward , backward , stop ( brake - which is the 0 degree thing you speak of)
                   

Youll see the servo speeds in the code for the $50 robot. Just figure out what speed sets the servo to zero,  then offset the rest.

interesting . . . someone had suggested this before too, but no one had actually tried to verify it . . . thanks!
