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.
