I am very inexperienced with electronic circuits and this is my first arduino project. I am having trouble with the schematics I am following for a project. [Magnet Levitation with Arduino - Arduino Project Hub]
The schematic shows two power supplies, but the parts list shows only 1. The schematics are represented differently in the fritzing diagram and the shield. I am not buying the premade shield and building this out on a breadboard. I am not understanding how to route a single power supply to both the electromagnet and the arduino.
