Instructions:
Prepare Components[^what-is]: Gather all components and ensure they match the schematic.
[^what-is]: what really is a component anyways./
Place the 7805 Regulator: Position the 7805 with its flat side facing you. The left pin is input (9V), the middle pin is ground, and the right pin is output (5V).
