I strongly recommend to avoid Fritzing diagrams. They are confusing, misleading and even in the best cases difficult to interpret. Component values are particularly difficult to represent or discern and plug-in breadboard connections, such as common power and ground, are often not shown or are misleading. Transistor leads, such as E, B, C or S, D, G are usually not identified, so the intent of connections to them are unclear. Fritzing diagrams are completely useless for complicated projects.
Fritzing diagrams are fine for complete beginners (think grade school) and the very simplest projects. They may look cool but are most definitely NOT an improvement over standard schematic diagrams; even hand drawn schematics are superior for unambiguous communication of circuit designs.
In short, except as noted for rank beginners, Fritzing diagrams are generally a bad idea and a step backwards.
