\section{Circuits Subsystem}
\subsection{Problem Assessment}
The circuit elements of the device serve four purposes: to provide each element of the machine with the required electrical power for operation, to trasmit command signals from the PIC microcontroller to the electromechanical components of the machine, to detect light, and to communicate the signals detected by the light sensors to the PIC.
The circuitry can be broken down accordingly: the sensor array for detecting light, the servo motors driver circuit for turning the candlelights on/off, the stepper motors driver circuit for raising/lowering the sensor array, the signal hub for interfacing with the PIC, the illumination LEDs for presence detection, and finally the power supply network, which is a machine-wide system, not a subcomponent.
The primary problems were electrical interference between subsystems, and miswiring arising from the complexity and breadth of the electrical system. Interference was overcome by compartmentalizing the electrical system so that units operated independently of eachother, mitigating a cascading failure effect. Correctly connecting subsystems together was accomplished by careful labeling and organizing of wires.
