I have just bought a MG90s tower pro servo for my school project and there is a problem. As soon as I connect my servo to the cnc shield or directly arduino, the whole arduino board turns off. I believe the motor is aking very high power. I even tried to power the motor with a 5v 2amps adapter, but still it turns off.I checked the resistance between the input wires and the wires to DC motor which was very high. As soon as I connected motor to external supply, there was a huge voltage drop. The voltage became almost negligible. DC motor was working fine alone. The servo hasn't even rotated for 1 degree. Please give me a quick solution as I am in a hurry for school deadline is coming. Should I buy a new servo or am I doing something wrong?
Please be quick.
Thank you.
Please don't cross post!

I have reported this thread to the moderators.
Duplicate posts waste the time of the people helping you. I might spend 15 minutes writing a detailed answer on this thread, without knowing that someone already did the same in the other thread. This behavior is not very respectful to the people you're asking for assistance. Just because we give our time freely doesn't mean it has no value.
In the future, take some time to pick the forum section that best suits the topic of your question and then only post once to that forum section. This is basic forum etiquette, which you would already know if you had read the sticky "How to use this forum - please read." post you will find at the top of every forum section. It contains a lot of other useful information. Please read it.
It sounds like you're doing something wrong.
For starters you obviously failed to read the sticky or you would have known what to post for an informative answer.

Gosh. Shoulda started sooner huh. Well, it's never too late, but you've got to slow down and work methodically - thrashing around at this point will lead to abject failure.
First thing, draw a clear picture of how you are hooking up your servo - have you followed the directions here?
Then show your code - try the demo code first.
Then come back and tell us how it worked.
