10 Ways to Show Your iPad on a Projector Screen
If you don't mind keeping your iPad in one spot, then a VGA adapter (for 30-pin Dock connector or for the new Lightning connector). Apple has made four types of adapters – determine which one you need. Or, a document or USB camera might work for you. If you want to wirelessly transmit your device's screen and audio so that you or your students can walk around the room, then it gets more complicated. You'll tap into Apple's AirPlay feature that is built into all iPad 2s and newer, including iPad mini. AirPlay works over Wi-Fi and requires all devices using it to be on the same network (unless you're using the newest Apple TV and iOS 8–then you can use a peer-to-peer connection). Apple TV is a small black box that can connect to a projector. iPad can mirror wirelessly to Apple TV using AirPlay. If you already have a computer connected to your projector, you should look into using software to turn that Mac or Windows PC into an AirPlay receiver.
