Assuming you would like to connect your iPhone to a Disney projector:
There are a few ways to do this. The first is with an Apple TV and the second is by using AirPlay.
If you have an Apple TV, simply connect it to the projector with an HDMI cable. Once it's connected, open up Control Center on your iPhone and tap Screen Mirroring. Select the Apple TV from the list of devices and your iPhone's display will appear on the projector screen.
If you don't have an Apple TV, you can use AirPlay to mirror your iPhone's display wirelessly. To do this, make sure that both the projector and your iPhone are connected to the same Wi-Fi network. Then open Control Center on your iPhone and tap Screen Mirroring. Select the projector from the list of devices and your iPhone's display will appear on the projector screen.
