Servo TowerPro SG90 9g doesn´t work. Help please.

I bought TowerPro SG90 9g servo. I connect it to Arduino, I uploaded a Sweep sketch from examples and it didn´t do anything. It only make some silent voice, but anything else. I think it can be inflicted by bad Degree Dead Band Width setting. But I don´t, how to do it. Can anyone help me please?

  1. Post -your- code (use the # in the editor!)
  2. Post -your- schematic (if you have one)
  3. Post a picture of -your- setup

I have everything like there is. http://arduino.cc/en/Tutorial/Sweep

Broken servo?

Cheers, Kari

I´ve 4 of these servos and all of them make this:D

Then your subject is probably wrong?

Do you think, you should show us how you connected them, somebody suggested you should show the code you are using, and a picture of your circuit?

Cheers, Kari

Sorry,I´am stupid. I haven´t it connected correctly. But thank for patience.

There’s a couple reasons why we ask people to post -their- code and -their- hookup (picture, schematic, both):

  1. It makes it much easier for us to diagnose problems and point out solutions
  2. It makes it easier for others, having a similar problem, to see what those solutions might be

As it stands - you’ve stated “I have a problem”, then when asked for -your- implementation, you pointed us to -someone else’s- implementation saying “I hooked it up just like that” - only to later state “I didn’t hook it up correctly”.

But at no point have we seen how you hooked it up -wrong- and how you corrected it. If someone else out there was facing a similar problem, this thread is effectively a dead end for them. I know when I’ve come across similar “dead end” threads on the net (usually for some obscure PHP or javascript issue in the course of my employment), where someone has a problem, asks for a solution, one or nothing is provided for them, then they respond “Ok - I fixed it - not with the solution you gave me but with something else - thanks!” - it makes me wish there was a button on my keyboard that I could press to smack the poster.

To anyone else coming to this thread hoping to find a solution to your issue: My appologies - I hope you are able to find your solution elsewhere…

Probably forgot to common the ground.

Gobb , I also have the same problem.. which wire colour is for ground,power supply and arduino pin? can u show picture of the working servo

Generally speaking, black/brown is ground, red/orange is + power, and white/yellow is control. Also the center wire is generally the + power to prevent damage if the servo connector is reversed when plugged into servo pins.
