Hi
I would like to know if there is a step-by-step tutorial for the servos from the Adafruit motor party package.
I know the ladyada site(http://ladyada.net/make/mshield/use.html)
I know the arduino site(http://arduino.cc/en/Tutorial/Sweep)
But since the Motor party servo comes with 3 color connector and the tutorial on arduino (which I tried and did not work) comes with another setup (without motorshield), it would be fantastic if there is somewhere a simple tutorial on how to make the servo move.
Any answer would be fantastic.
Thanks
L.

Re: Motor Shield Ladyada
Did you try the Lady Ada Tutorial too?
Both tutorials do work. Post a photo showing how you have things connected.

Re: Motor Shield Ladyada
Thanks for the quick reply.
I managed to make it work now! Yeah!
My error was on the motorshield there are two servo connectors and after I plugged it in the other one it did work.
It seems the second connector, connects it just like in the arduino tutorial to pin 9.
For some strange reason my LED on the motorshield does not do anything.
Does anyone know when it should be blinking? (Upload, motor running..)
I hope I did everything correct.
But this was only a test anyway.
Now I would like to get my ultimate goal the stepper motor going.

Re: Motor Shield Ladyada
The LED on th emotor shield indicates motor power to the H-bridge chips. It is not related to servo operation, but you will need it for running steppers.
Read "How to set up the Arduino + Shield for powering motors" on this page.

Re: Motor Shield Ladyada
Hi
I connect the servo supplied by the motor party kit to the second servo 3 pin connector and run the Sweep example found in Arduino-0022/libraries/servo
I can hear the motor making some noise, but it doesn't move.
I am using an external 5V power source for the servos.
The Arduino uno is powered by the usb cable?
The sweep sketch assumes the servo is connected to pin 9.
How do we know the motor-shield has done that?
For some reason, nothing works(not even sound) if i connect the servo to the first servo connector(the one at the edge of the board)? Is it connected to some other pin? Some details would be useful.
Thanks
Sam

Re: Motor Shield Ladyada
It is not possible to power the servos with external power without modifying the board. The 3-pin servo terminals draw power from the Arduino 5v regulated supply. Since you are powering it with USB, it will be limited to about 500mA, which may not be enough to drive some servos. If your external 5v source is regulated and can supply more current, you might have better luck using that to power the Arduino.I am using an external 5V power source for the servos.

The motorshield servo ports are connected to pins 9 and 10 as described in the FAQ and shown in the schematic:The sweep sketch assumes the servo is connected to pin 9.
