Electronic – Basic microcontroller + RF transmitter/receiver plausibility

communicationmicrocontrollerRFwireless

I am a complete beginner (I have only gone through the beginners book to Arduino + done a few small projects). I want to know if it's possible to connect a very basic/cheap microcontroller like the MSP430 to a RF transmitter (for example this one) and another microcontroller to a RF receiver, add power supplies, some code and have them communicate (I am going to add a buzzer later). I also only need the receiver to acknowledge that it is receiving a signal. Data is not very important (i.e. 1 bit is enough).

Am I being naive/leaving something out/making a mistake? I understand resistors, diodes, etc. and c++, but have no idea of the rest of the world of electronics…

(By the way, the reason I chose the cheap parts is because I'll eventually need loads of them).
(Also, is there a cheap RF transmitter/receiver built onto/into a microcontroller?)

They make a msp430 with a built in rf transceiver. They call them the CC430. There are many others. All that you've said you want to do is possible ;)

Also their EZ-RF kit is pretty easy to use and fun to play around with: enter image description here

I think I got all mine free but it looks like they're only $49. There are bunch of other guys like microchip who make micros + RF solutions.
