Robotic Piano - Circuit Diagram

A circuit diagram (electrical diagram, elementary diagram, electronic schematic) could be a graphical illustration of an electric circuit.
A pictorial circuit diagram uses easy pictures of parts, whereas a schematic diagram shows the elements and interconnections of the circuit exploitation standardized symbolic representations.
Unlike a block diagram or layout diagram, a circuit diagram shows the particular electrical connections.
A drawing meant to depict the physical arrangement of the wires and also the parts they connect is termed design or layout, physical style, or schematic drawing.

Real Time Circuit Diagram

In electronics, a circuit is a path between two or more points along which an electrical current can be carried. (A circuit breaker is a device that interrupts the path when necessary to protect other devices attached to the circuit - for example, in case of a power surge.)
In telecommunications, a circuit is a discrete (specific) path between two or more points along which signals can be carried.
Unless otherwise qualified, a circuit is a physical path, consisting of one or more wires (or wireless paths) and possibly intermediate switching points.
A network is an arrangement of circuits. In a dial-up (switched) connection, a circuit is reserved for use by one user for the duration of the calling session.
In a dedicated or leased line arrangement, a circuit is reserved in advance and can only be used by the owner or renter of the circuit.
