My Arduino arrived yesterday and so far, I have blinking LEDs, singing piezo, knock sensor etc. All very interesting. However, I am pulling my hair out with the servo example from the playground.
When I upload the sketch, the servo does noting. (Expected :)) When I send a 90s, the servo goes all the way to the limit and "quivers" there. There is considerable load (not measured but the 7805 heats up rather quickly)
I have tried a number of different demos but to no avail. They all do the same to the servo. Could it be the pulse width that is wrong? I thought they all standard. I have tried playing with various different values but that too has had no effect.
The servo is a Futaba 3010. According to the tech spec, it's neutral pulse width is 1250usec.
Any help is appreciated.
