OK for my PING))) Turret I'm on PULSOUT 14. MY PING))) sensor is on 15, and my left and right servos are on 12 and 13. I want to use the gripper servo as well! What I need is a way to use a PULSOUT say 11 or 16 command from the breadboard I know how to to place a servo on the #15 of the bredboard for the ping, but can I use another 10,11,or 16
and if so, can you show me by editing the enclosed BMP I'm not to great with Schematic Diagrams! OK thats a understatement I'm totaly lost!!!LOL And before you say use a servo controler I,m dealing with limited space on my Boe and The fabrication Ive used dosen't have the room!
thanks Guys I LOVE YOUR TOYS!!!!!!!!!!!!!!!!!!!

    The WAM manual shows how to wire a servo header on the Homework board, which doesn't include built-in servo headers. You can do the same thing with the BOE.

    Zax,
    Any pin can be used to control a servo. You just need to indicate which pin you want to use in your PULSOUT statement.

    Or am I misunderstanding your question?

    Except 16...Since that is a virtual port used only in the SERIN/SEROUT commands.

    Here is a pic of my boe as you can see my PING))) sensor is on the breadboard.
    So I cant use the pulseout 15 command for the gripper in the by pluging it in the built in servo header as I,m sure that would create strange results! confused.gif
    Thanks Guys

    Look at the Whats a Microcontoller manual. Bottom of the page here http://www.parallax.com/detail.asp?product_id=28152.· It explains how to hook a servo to the breadboard, using any pin.

    Hi Zax,

    look at the attached picture.

    Change the port wire connection (blue wires in the picture) to the desire port (like 10,11 as u have stated earlier or any other port pin which is free).
    The only thing required are the three pin header to connect the servo wire jack·on the breadboard.

    Alternatively, Instead of port 15 u can change·PING wire connection to port pin 11 or any other free port
    and place the gripper servo to the·SERVO PORT·header 15
    and·replace·15 with 11 in the coding(or as per your port selection).

    Hope this helps.........
