Wireless LCD display
Now this is a good project with a good code snippet. It allows you to send data over IR link to a remote LCD character display. So, it's a wireless LCD display!
Part count for this device is very minimal. On the transmitter side we have a PIC16F688 microcontroller with 5V power supply and HSDL-1100 IR transceiver module used only for TX. At the receiving side there is also a PIC16F688 with HSDL-1100 module and LCD display with KS0070B controller.
So if you need to send some text wirelessly - this is the way to go.
