For this question, you need to use the

force sensor in Tinkercad

It should be connected to an Arduino in

the following configuration:

FSR $=$ force sensor$,$ it works as a variable resistor

Write a program to collect data to determine the

relationship between the number measured by the

Arduino and the force value on the force sensor$.$

You should collect data points every $0\mathrm{.}5N$ up to

$5N,$ and then every $1N$ up to $10N.$

You should then either use polvfit in MATLAB to

fit the data with a polynomial equation $($of $4^{th}$

order or higher$)$ describing the relationship

between the $2$ variables. You will then use the

resulting equation to convert from the number

read by the Arduino to force in N$.$

OR

You can use a look$-$up table. You can store pairs

of measured Arduino input$/$force in $N$ in columns

in a matrix, where the Arduino input numbers are

organized from lowest to highest. To then convert

a new number read in by the Arduino $($x$),$ find the

the Arduino inputs and $x_2)$ in your table that

bracket your value, i$.$e$.,$ closest to $x$ above and below

it in value. Then use linear interpolation with $x,x_1,$

$x_2,$ the corresponding force in $N$ in the table $y_1$ and

$y_2$ for $x_1$ and $x_2$ :

$y-y_1=\frac{y_2-y_1}{x_2-x_1}**(x-x_1)$
