Am new to rf circuits,ie. only of little knowledge.
I need a radio controlled (rf) transmitter/reciever circuit pair.
I need to operate a led, dc motors and other small appliances. To turn on and off.
It may be Working in the frequencies of 27mhz, 35 r 45 mhz. or as suitable
of my question. The lenght range of my tx/rx can be of few meters
from 4-5mts.
The overall circuit voltage is of a small operating voltages.
3-5v for transmitter and 3-6v for receiver.
Only a basic simple form of circuit i need.
Because i need both to be small in size.
needed:
The transmitter can have a single switch r button.
The receiver must r just give an output of a single pulse
whenever the transmitter button is pressed.
The output pulse will be used to trigger a flip flop for turning the
rest of the circuit for power control.
If the rf is not suitable and if any other wireless can be used also ok. And i neglected ir since it needs line of sight even it is simpler and cheaper.
And dont know of anyother wireless types.
Only i need is wireless, small distance , without line of sight (passing opaques),low voltage, a reciever output of a single pulse and simple components circuits of getting easily.
And i would be thankful of own circuits instead of websites or exact websites of my critiria, since am tried of surfing the whole nets,googles and i dont know how to find it.
any other suggestion is also welcome.
