Anyone here now how I can solved that problem?
I have written a post covering the most common servo mistakes, it might not be exhaustive, but its a reasonable first draft, see here -
Hi,I was able to drive four hobby sized servos from an Arduino with a PP9 battery. I took the trouble to stall one of the servos to ensure it was pulling reasonable current and the system was still happily sweeping away.Good for you. But many have problems powering even one servo using the arduino's 5v pin and using PP9 sized batteries, we see the posts here all the time from fustrated beginners. The lesson is that the arduino board is very good at controlling things, but at powering things, not so good. Its not a long term solution it does have problems but in order to get people over the first hump it works.But many won't see it as a short term only solution and still base their servo application on using such a unreliable power source.If you had read one, I get to power eventually -I am in the process of rewriting the whole thing for clarity.Duane B.
I can accept that and will take it into account for the rewrite.
