Master Wiring Diagram

ALT Wiring Diagram

AboveĀ is the Master Wiring Diagram. This schematic details all the electrical connections required for the ALT project. Additionally, it labels all the micro-controller pins required. The Arduino Mega is used to process all I/O functions, while the Arduino Yun manages data-logging functionality.

Sub-systems have been kept together and connections spaced out to aid debugging. Certain time critical functions are attached to interrupt pins, such as the Door switches and safety resets.
Finally, as a fail-safe, certain sensors report to both the Arduino Yun and Mega. This allows either micro-controller to reset the other in case of an error or lock up. Each processor also has control of safety critical functions and can cut power if required, minimizing risk.
