2 Channel RF AVR Remote Control -  How many times you needed some remote control to handle some electric device ? many times.  There are lot of remote controls like infrared, RF, SMS (like my other circuit) and more.  The basic small-range remote controls are 2, infrared and RF (Radio Frequency).  One of the weaks of infrared is that the signal can not pass the walls.  So, if you want to control your garage door, the only way is to use some RF remote control.  The circuit (transmitter and receiver) use few components and ordinary (I love few component circuits).  its easy to build it because you don't have to tune-up any coil or variable capacitor.  The RF modules are fix to work in 418MHz area.  __
