How to Make a Schematic for Your Electronic Circuit Project

Electronic circuit design can range from a simple task for the home hobbyist to a highly complex project requiring teams of designers. A simple project may not require a formal design process but other aspects are similar to those performed by professional circuit designers. The following steps will show how to make a schematic for your electronic circuit project.

Instructions

Difficulty: Moderately Challenging

1. Choose a project. You will already know what you want to build if you are filling a practical need. However, if you simply want to practice building electronic circuits, you may want to select one of the many thousands of home electronics projects that are available.
2. Examine the functions of electronic components. Basic components include a resistor that limits the flow of current to a specified level and a diode that glows when current is applied to it. A battery is usually the power source for home projects and wire also will be required.
3. Learn the necessary symbols. Each component of an electronic circuit is represented by a unique symbol. For example, a resistor is drawn as a sharp wavy line like a "W" and a diode is represented by a triangle with its apex pointing in the direction of current flow.
4. Draw the schematic design on paper. This stage usually involves making changes to the design as you resolve design flaws. You will tend to consider each component individually at first but as you become more proficient, you should develop the ability to visualize the entire circuit.
5. Build a prototype to verify your design is correct. A breadboard or some other prototyping material will allow you to easily test your circuit's actual behavior to its predicted behavior.
