POV Clock- Need a way to wirelessly send messages

I'm building a POV clock but one of the requirements is to be able to send a message to the clock to display while its spinning (around 10 characters).

We are planning to use a PIC microprocessor with c programming etc. The PCB hasn't been built yet but wondering what kind of device I could use to connect to the POV clock so I can achieve this? We'll be using about 10 LED's.

Someone has recommended a Bluetooth receiver module the HC-03 which I am unsure about.
Thanks

Hello,

Bluetooth is very cheap now so this could be a very easy option. I used IR on my POV display but had issues receiving reliable data because of all the noise on the supply rails.

Have you seen this topic?

Thanks for the reply, I have bookmarked that link previously and using it for further reference for other parts of my project. Mostly though I'm stuck on the sending wireless signals to the device to get it to show messages.
