I need my trigger to fireonly when a checkbox field changes 'unchecked ' to 'checked' not the the other way around.. I can't think of anything.

See if below code helps, 
if (Trigger.isUpdate){
            for (YourObject obj : trigger.new){
                if (!(Trigger.oldMap.get(obj.Id).ChecboxField__c) &&  obj.CheckboxField__c){
}
}

if(trigger.oldmap.get(opp.Id).opp.CheckBoxField__c == false && opp.CheckboxField__c == true){
 //run your script here 

}

}
