    Dear Members,

    I would like to ask for help, to design simple function remote control.

    the need:
    potentiometer which control on transmitter, and transmit signal to receiver. and receiver generate analog output of 0-5V (about 0.1V steps) to control some amplifier.

    i was thinking about bluetooth technology, because low power consumption on the transmitter side is very important.

    where i can start ?

    Thank you in advance.

    How to telemeter the pot position depends on what you are going to use for the RF link. I would use commonly available OOK receiver and transmitter modules that operate on 433MHz and use PWM to encode/decode the pot position.
