$\%$ Now we normalize the current flex reading to a range between $0$ and

$\%255.$ Let's compare ratios $($in this case, read reflects our ADC, and

$\%$ targ reflects the RGB range$)$ This is called linear interpolation:

$\%($readVal $-$ readMin$)/($readMax $-$ readMin$)=($targVal $-$ targMin$)/($targMax $-$ targMin$)$

$\%$ Rearranging:

$\%$ targVal $=(($readVal $-$ readMin$)/($readMax $-$ readMin$))*($targMax $-$ targMin$)+$ targMin

$\%$ Now let's take a reading from the flex sensor$.$ We want to ensure our

$\%$ value is within the range we declared in order for our linear

$\%$ interpolation to work.

flexVal $=$ nb$.$analogRead$(\text{'}$A$1\text{'})$;

if flexVal $>$ flexMax $\%$ if flex reading is greater than maximum reading

flexVal $=$ flexMax; $\%$ set to what?

elseif flexVal $<$ flexMin $\%$ if flex reading is less than minimum reading

flexVal $=$ flexMin; $\%$ set to what?

end

$\%$ Time to linearly interpolate the RGB value from our flex reading.

rawRGB $=((\text{'}?\text{'}-\text{'}?\text{'})/(\text{'}?\text{'}-\text{'}?\text{'}))*(\text{'}?\text{'}-\text{'}?\text{'})+\text{'}?\text{'}$;
