hi,
i want to actuate 2 servos synchronously. if i connect them and boot, the arduino seems to reboot again and again.
is there a chance to do this or do i have to do this with code?
greetz and thx 
are you connecting them directly to the arduino? if so your drawing too much current and the low current is resetting the board (and could be frying something)
Make sure you're powering the servos separately (fout AAs should do the trick).
Don't forget to connect the grounds of the battery pack and the Arduino together.
The servos are probably drawing too much current, and pulling down the voltage on the arduino, causing it to reset.
