Title: Servos and Arduino Duemilanove
Post by: Siretu on July 09, 2009, 07:03:49 AM

I just bought a http://arduino.cc/en/Main/ArduinoBoardDuemilanove (http://arduino.cc/en/Main/ArduinoBoardDuemilanove), however I'm wondering where to connect my servos. There's 6 pins but it doesn't seem to fit and I don't want to force it.

Did I miss something? If so, what? If not, where do I connect the servo? Can I take some metal pins and insert in between the servo contact and the slots on the microcontroller.

to connect a servo you will need something called a shield.
the arduino has a female header with no power bus. the shield makes it so there is a male header with a power bus.

alternatively for a quick fix, you can stick wires down the servo connector and jumper it over to the female headers...
you will take the yellow (signal) wire from the servo to a digital pwm output on the arduino (pin 9/10/11)
the red wire will go to unregulated power (make sure your battery pack isn't higher than 7.2V)
the black wire will go to gnd on the arduino.

heh heh, precisely why I created the Roboduino

I personally would get a perforated circuit board and make my own shield . A servo shield is probably the simplest one possible.

Thanks for the replies, I'll try it with wires and I'll order a shield as quickly as possible.

for the mean time you can use jumpers from the servo cable to the arduino..
this is why im glad to have a roboduino!
