Before you leave court after any court date, (arraignment, pre-trial conference, trial, or other date) make sure you understand what happens next. Do you need to come back for another court proceeding? Do you need to prepare anything in writing for the next court appearance? Do you need to take other steps or actions? Will the judge make an order as a result of the hearing? Sometimes orders are written up right away - as you wait. Or, the judge may write an order later and send it in the mail. Politely ask questions if you do not understand what will happen next.  

Specifically, 1) know how to contact your lawyer; 2) make sure you know when to come back; and 3) make sure you know about any conditions of release (the probation department can help you understand the conditions).
