Write an Arduino code for this circuit:

$-$Utilize a joystick to manage the RGB module

$-$The joystick directions $(larr,$uarr,$)$ control the color mixing: larr for Red, uarr for Green, and $$ for Blue.

$-$The down direction $(darr)$ confirms the chosen color mix and lights up the module.

$-$The joystick switch turns off the module.

Examples:

$(larruarr)$ results in $(256,256,256)$

$(larrlarruarruarr)$ results in $(256,256,256)$

$(larr)$ results in $(256,0,0)$

$(larrlarruarr)$ results in $(256,128,128)$

$-$Note: The joystick must be moved more than halfway in any direction $(larr,$uarr,$,$darr$)$ before recording the color.
