Programming help - static lookup table

I'm new to programming so any help is very much appreciated.
I have a 0-5v input, consisting of 60 x 0.083v steps.
I need to monitor this input voltage and, referencing a static lookup table, vary an output voltage.
Basicly converting a linear input to a logorithmic curve output that i can alter by editing the lookup table.

Any code examples would be very helpful. Thanks

There are video tutorials in Youtube. You can check there how to use and arrange codes that you are looking for. You just have to make sure that you choose the best tutorial to make things faster and easier.

Thanks, can you recommend one? There are so many it is confusing.

Unless there's any interpolation, it is a simple array access, isn't it?

Isn't is just this?

analogWrite(60byteArray[x]);

with
60byteArray[0] ={number_from_0_to_255};
60byteArray[1] ={number_from_0_to_255};
60byteArray[2] ={number_from_0_to_255};
:
:
60byteArray[58] ={number_from_0_to_255};
60byteArray[59] ={number_from_0_to_255};

and map your 0-59 into 0-255 along whatever curve you want to use.

CrossRoads, Many thanks although I'm still confused. Would you be willing to work with on this with me? I noticed you do design-build; I have some funds available and really need the help.

Sure.
With
analogRead(analogPin) you get a reading back between 0 and 1023, with each increase representing a 4.88mV change
With 83mV steps, that works out to a step change about every 17 steps
On the output side, you need to define the curve you want

0-16 will be step 1 excpected
Start end step PWM output voltage
0 16 0 4 = 4/255 * 5 = 0.083
17 33 1 9 0.167
34 50 2 13 0.250
51 67 3 17 0.333
68 84 4 21 0.417
85 101 5 26 0.500
:
:
969 985 57 247 4.833
986 1002 58 251 4.917
1003 1019 59 255 5.000
and change 1019 goto 1023 for the end

OK, I may be getting it. I'll work with this over the weekend. Will get back to you after. Many thanks
