The purpose of an arraignment is to advise you of the charges against you and to set conditions of your release (or continued release if you are not in custody at the time of your arraignment).
Your lawyer and the prosecutor will exchange paperwork concerning the charge, bond issues, release conditions and such.
The Judge will ask how you plead to each count against you and enter not guilty pleas into the record. The issue of OR (own recognizance) or bond will be addressed and court dates will be set. Release conditions will be set (where you are to live, don't leave the county, maintain contact with your attorney, do go near the other people involved with your case, et cetera.
You will be given a copy of the court dates that have been set before you leave the court. Don't lose the date; if you were to forget to come to court at your next court date a warrant will most likely issue for your arrest.
