I have a project, for me to control multiple electrical appliances at the same time, wirelessly.
so i am thinking of having a transmitter circuit, which will actually transmit the on off commands (signal) with different carrier frequency, so that each frequency will corespond to only one receiver.
I am thinking of using ASK since the input of this transmitter will be logic levels 1 and 0 ( 5V and 0V).
can anyone provide me the link for the circuit diagram of such device that can send out signal with multiple carrier frequency, or even if you have a better suggestion.
thank you.
