Hi everyone,
Project Idea:
When I'm driving in my car and someone is on my tail, I want to be able to press a button that will wirelessly send a signal to a portable LCD (placed inside my car, in the corner of my back car window) that will display a message of my choosing (something I programmed it to say).
------------------------------
What I Need Help With:
I currently already have a Parallax board which I can easily use to program different messages into the LCD.
Where I need help is, creating the transmitter portion of the project. That is, figuring out what components are needed to create a button that when pressed, it will send a digital wireless HI/LO signal to a pin on my Parallax board. Once I figure that out, I know how to do the rest.
Thanks!
