How to draw electronic schemes

Schematic diagrams are used to represent electronic elements and the design of electronic circuits with symbolic elements. It is necessary to understand the design of the circuit to draw a scheme . The Schemes are used to understand how a circuit works, the maintenance and repair of electronic systems and must be clearly established.

one

Draw the processing unit or main component for the circuit in the center of the drawing sheet. This will ensure that they branch uniformly to include other components connected to the device.

two

Draw the other minor components by using simple lines that represent the cables of the main components. All cables must be at right angles, as they lead to the other components. These include capacitors, resistors, power supplies and other electronic components.

3

Position the power supplies so that the positive pole is on top of the components and the negative pole is connected to the bottom of the circuit components. This ensures that the supply lines do not cross and can be labeled clearly.

4

Use schematic symbols of the components, such as capacitors, resistors and label them appropriately with their correct values.

5

Put a "bubble" in the cable junctions. Any connection should be made a distance away from the components for clarity.

6

Label the signal lines (for example, CLK or RESET), functional blocks and show any wave along with the appropriate component.

• When designing the scheme, try to organize the components in such a way that the input signals are to the left of the scheme and the output signals are placed to the right.
• Sometimes, it may not be necessary to include the power source or the battery and it may be omitted to avoid clutter. However, power lines must be included and labeled accordingly.
• A general schematic diagram will be drawn up so that the voltages in a circuit decrease downwards in it. This is the reason why the positive pole must be on the top and the negative pole on the bottom of any connection.
• Re-trace the circuit to ensure that all connections and components are included and that they have been properly labeled and no part has been overlooked or mismatched.
• To mark the symbols, make sure that the pin numbers are on the outside and the names of the signals are inside the symbol.
