I purchased an electronics kit from somewhere (cannot recall). It was very useful and beneficial.
The kit includes a BUNCH of components from sensors to motors to 7-segment displays.
For some lessons, the wiring diagram (i.e. the “Fritzing”) is included. This is different from the schematic as it considers how the connections are actually made. Additionally, the wiring diagram gives a visual depiction of the components rather than a symbol (like a schematic).
The wiring diagram helps to transition the circuit from schematic to a breadboard representation
