Is there a package for schematic representation of Arduino?

Question

I need to represent a circuit containing Arduino. I'm new to circuitikz, and to latex, so I'm not able to code a complex circuit component.

Welcome to the site. Can you help us by focusing your question a bit, and providing some code to show us what you have tried? — Steven B. Segletes, Feb 15 '19 at 12:06

I think there's no package for that, but you can create your own Arduino Uno component. I would recommend you to read CircuiTikZ Manual: https://texdoc.org/serve/circuitikzmanual.pdf/0, and read about LaTeX too (there're many online resources for that, just search in google).

After that, in order to create your own component, I would recommend you to check out John Kormylo's answer in here: CircuiTikZ — create new component. Following his Multipole Tutorial I was able to create this Arduino Uno Diagram for blinking a LED:

This is the code:

You don't have to create an exact physical represantation of an Arduino Uno if you don't want to, as long as you represent its pins in an understandable way it's fair enough. Either way, any suggestions on how to improve the aesthetics of my diagram (or my code) are welcomed

As a starting point, you can use the following code (It is not complete code for Arduino Uno and some components are not scaled).

\documentclass[margin=5mm]{standalone}
\usepackage{xcolor,circuitikz,tikz}
\usetikzlibrary{calc,intersections,positioning}
\definecolor{darkcerulean}{rgb}{0.03, 0.27, 0.49}

\tikzset{%
myarduino/.pic={
\coordinate (A) at (0,0);
\filldraw[very thick, darkcerulean] (A)--(66.1,0)-|(66.1,2.5)--++(45:2.5)--++(90:30)--++(135:2.5)--++(90:16)--++(180:66.1)--cycle;
\filldraw[very thick,gray!40](-2.5,3) rectangle (10,10);
\filldraw[very thick,gray!40](-6,40) rectangle (10,50);
\filldraw[very thick,gray](25,13) rectangle (63,20);

\foreach \x/\t in {26/RESET,29/3V3,32/5V,35/GND1,38/GND2,41/VIN}{
\node (\t) at (\x,3mm) [fill,draw,minimum width=3mm,minimum height=3mm]{};
\node at (\x,5mm) [xshift=2.5mm,above=8mm,rotate=90]{$\mathbf{\t}$};}

\foreach \x/\n in {46/0,49/1,52/2,55/3,58/4,61/5}{
\node (\n) at (\x,3mm) [fill,draw,minimum width=3mm,minimum height=3mm]{};
\node at (\x,3mm) [above=3mm]{$\mathbf{\n}$};}
}
}

\begin{document}
\begin{tikzpicture}[x=2mm,y=2mm]
\pic at (0,0) {myarduino};
\draw[very thick] (GND1)--++(-90:10);
\draw[very thick] (RESET)--++(-90:10);
\draw[very thick] (1)--++(-90:10);
\draw[very thick] (4)--++(-90:10);
\end{tikzpicture}

\end{document}

Is there a package for schematic representation of Arduino?
