\appendix
\chapter{Procuring the Hardware}\label{shield-appendix}
One may need some or all of the components listed below to carry out
the experiments explained in the book:
\begin{enumerate}
\item Arduino Uno
\item Components required to build the Shield
\item External actuators that work with the Shield
\item Components required for the breadboard based experiments
\end{enumerate}
We now provide an approximate cost of the above parts, mainly to keep
a beginner informed, see \tabref{tab:cost}. Because of the
fluctuations in exchange rates, and the availability issues, pricing
could change considerably.
\begin{table}
\centering
\caption{Approximate cost of the components}
\label{tab:cost}
\begin{tabular}{|p{5cm}|c|}\hline
Item & Cost (\rupee) \\ \hline
Arduino Uno & 675 \\ \hline
Components for the Shield, given in \tabref{tab:shield-values} &
350 \\ \hline
External actuators (motor, motor driver, servo motor) to work with
the Shield & 400 \\ \hline
Half breadboard & 250 \\ \hline
Components that go with the breadboard & 700 \\ \hline
\end{tabular}
\end{table}
With the components and the Gerber file mentioned in
\secref{shield-hw}, it should be possible to create the PCB, and
solder the components, so as to arrive at the Shield, as
shown in \figref{shield}. This is the least expensive option.
% A lot more expensive option is to request the FOSSEE Team to create a
% shield and to supply it. It is a lot more expensive, because the cost
% of the manpower who will make the shield is also to be factored. As
% this work is not a part of IIT Bombay's regular activity, it has to be
% carried out through personnel specifically employed for this purpose.
% The FOSSEE team has a limited supply of shields, available at
% \rupee1,000 each. Interested people may contact
% \href{mailto:FLOSS-arduino@fossee.in}{FLOSS-arduino@fossee.in} or at
% +91 22 2576 4133. As mentioned above, the cheapest way is to make the
% shield by oneself, by procuring the components and making the PCB.
The readymade Shield is also available on E-commerce websites like Amazon \cite{amazon-shield}
and Flipkart \cite{flipkart-shield}, in the name of Ecolight\textregistered \ Sensor Shield V-1.2
Compatible with Arduino Uno R3.
% Interested people may contact
% \href{mailto:FLOSS-arduino@fossee.in}{FLOSS-arduino@fossee.in} or at
% +91 22 2576 4133.
Latest information on Procuring the Hardware is available at \url{https://floss-arduino.fossee.in/}.
One could also contact us at \href{mailto:FLOSS-arduino@fossee.in}{FLOSS-arduino@fossee.in}, but the response could be slow.
% In addition to this, if you write to us at the above email address,
% we may be in a position to give details of vendors who can supply the above components, and
% also the shield. The advantage may be that these vendors may be able
% to supply these components and the shield at a price lower than that
% of FOSSEE. In case the readers know about some vendors who can meet
% this demand, please let us know and we will be happy to include them
% in our list.
