In this video I am showing, how to make 12 channels Receiver by using Arduino nano. This 315mhz rf receiver has 12 channels. It can convert this 315mhz remote control circuit for 433mhz by using 433mhz rf receiver module.

12 channels transmitter    • The Hidden Power of Arduino: Arduino ...  

. This circuit can be use for various remote controlling applications like DIY remote control car, radio control trucks, rc boats , DIY rc toys, rc fans etc.)
The circuit will scan the pressed button and then prepare the transmitting message and transmits it.

The transmitter works one channel at a time in this version. although some channels work simultaneously without issues.
