We have to do some extra efforts with setting the value from controller. 
Please check the example below : 
In this example I am having a picklist of months and I want to change the selected value dynamically.
Component

1 2 3 4 5<lightning:select value="{!v.selectedMonth}" aura:id="selectMonth" label="Select Month" onchange="{!c.changeMonth}"><aura:iteration items="{!v.picklistValues}"var="item" indexVar="index"><option value="{!item.key}">{!item.valu…
