First the second servo don't want to turn correctly, and after a couple times it turns smoothly. I've checked the pcb print from servo one and two and these are not identical.
The first one works correctly.
Thanks in advance
Never mind the fancy videos. Post your code - in code tags using the # button so it looks like this

Oke I think that i need the external power supply for the arduino board.
And the arduino code is correct from the standaard samples.
i think that the beep com from the usb disconnection
Best regards

Servos (and other motors) should NOT be powered from the Arduino 5v pin.
It never ocurred to me that "peep" in your title was mean to be "beep" - there is only one letter difference but they are very different words. If you go back to your original post and click modify you can correct the title.

Ops sorry my keybord is very small on my galaxy.
Today I bought an external adapter and I also connected the USB cable and then I want to upload something and I get the message "avrdude stk500_getsync () not in sync resp = 0x00"
I use 9 volt for the arduino uno R3 power jack.
Before I plug the 9 volt connector to the arduino board the upload working well and the TX and RX leds are blinken well when i upload the code.
Now when i connect the board the green led is on and also the L orange led is on, and when I upload the code no leds are blinking from the TX and RX.
Anyone have an idea to solve this problem?
Thanks in advance

It sounds like you have no problem uploading code with the USB only connected and you do have a problem when the USB is connected and the 9v supply is connected. The solution seems self evident.
What sort of 9v supply are you using - a PP3 battery is useless and a wall wart should be able to supply 1 amp.

Typical way to power a servo.
