on video How To Make RF Remote Switch

  make a 433 MHz RF remote control transmitter & receiver circuit. 

Here I used HT12D & E pair IC, 433 MHz RF RX,TX pair & some electronic components.

The circuit diagram is included in this video.   

You can use this circuit to make radio control car, Robotic projects, Home automation & other Rf communication  purpose.

I used 433Mhz RF modules in this circuit. With the RX470-4 transmitter and WL102-341 receiver module, it is possible to reach a range of 100 meters in ideal conditions. This range is more than enough for small RC model vehicles. Longer range can be achieved by using different RF modules in the same circuit. In theory up to 4km is possible.
