    Hi all,
    Can any body give me the ide how to make electronic circuit with input and output below:
    Input: Output:
    5 volt----------------> 0,5 volt
    4,5 volt-------------> 1 volt
    4 volt---------------> 1,5 volt
    3,5 volt-------------> 2 volt
    3 volt---------------> 2,5 volt
    2,5 volt------------> 3 volt
    2 volt---------------> 3,5 volt
    1,5 volt------------> 4 volt
    1 volt---------------> 4,5 volt
    0,5 volt------------> 5 volt
    please sent to my email the design [email protected]
    Thank you

    It seems that you need a simple inverting op amp with unity gain (-1) and a virtual ground offset to +2.75 volts. Choose an amplifier & power supply so the linear operating range includes 0.5 to 5 volts.

    You could use a micro, do an A/D then generate the appropriate D/A output value. Some of it depends on the power you expect to output of course.

    Use 2 µCs and sent the A/D converted Data from µC1 via Internet to µC2 to have it D/A converted.

    That was just so funny I couldn't reply any earlier I had to be hospitalised for a side split repair operation.

    Ok, here a bit more serious answer.
    This is your circuit (based on Laplace's answer):

    Right,
    forgive us for having some fun.

    Of course, that circuit is what's pefect for this job.
