Circuit design is the first step for all electronics design projects. It requires creating a schematic diagram that defines how electronic components logically connect on a printed circuit board (PCB). Engineers can perform SPICE simulations or translate their schematic into PCB design software when the circuit design is complete.
There are a host of electronic circuit building blocks. Electronic tutorials in this section provide practical and valuable guidance tips on electronic circuits, design information, principles, practical instructions, and electronic circuit building blocks.

Analog Circuit:
In analog electronic circuit designs, the information represented by current or voltage varies over time. Diodes, resistors, capacitors, and transistors and wires are the main components of an analog circuit. In analog circuits, electrical signals take a continuous value.
These circuits are dentes the schematic diagrams where lines represent wires, and separate symbols represent each component. Every analog circuit consists of a series or parallel or two circuits.
Digital Circuits:
Digital electronic circuit design takes electrical signals as discrete values. Zeros and ones represent data. Digital circuits extensively use transistors, interconnected to form logic gates that perform Boolean logic functions. Transistors are interconnected to provide positive feedback, as used in latches and flip-flops. Thus digital circuits can provide logic and memory, enabling them to perform calculations.
Schematic Circuit Diagrams:
A schematic circuit diagram represents the components and interconnections in a circuit using standard symbols rather than an actual picture of the component. Circuit diagrams design, construct and maintain electrical and electronic equipment. Although not standard, schematic diagrams are organized from top to bottom. Thus, the antenna is on the left, and the speaker is on the right in the signaling circuit. Similarly, the positive power supply is at the top of the page, ground and negative supply are at the bottom.
Electronic Switch Circuit:
A switch is an electrical device interrupting the current flow in a circuit. These are essentially binary devices that are either entirely on or fully off. Controls the working of the circuit along with on/off switches and activates different circuit features. Switches are mechanical devices with 2or more terminals connected to metal contacts. When contacts are together, then the switch is closed. Thus current flows, and the switch turns on. When the contact is separated, the switch is open, and no current flows.

Toggle Switch:
An angular lever actuates a toggle switch in one or more positions. The lever is rotated up or down to close or open the switch. An example of a toggle switch is a light switch used in a home.
Push Button Switch:
The push button switch is a two-position device actuated by a button to open and close contacts. The contact alternates between opening and closing each time you press the button.
Selector Switch:
Selector switches actuated with a rotary knob or lever to select one or two positions. A selector switch can rest in any of its positions, like a toggle switch.
Joystick:
A lever actuates a joystick switch to move in more than one axis of motion. The circle and dot notation on the switch symbol indicate the direction of the joystick lever motion required to trigger the contact. Joystick hand switches are used to control cranes, robots and games.
Liquid Level Switch:
A float activates a switch mechanism when the liquid level rises to a fixed point. The float closes the circuit when the liquid level reaches a certain point. This closed circuit conducts, it performs a specific task. Lever actuator limit switches, pressure switches, proximity switches, speed switches, and nuclear level switches are many other switches used in electronic circuits.
Electronic Circuit Design:
Electronic circuit design takes part in the analysis and synthesis of electronic circuits. While designing an analog or digital circuit, the designer must estimate the voltage and current at each node in the circuit. All linear and straightforward non-linear circuits can be analyzed using mathematical calculations. Software is used to analyze complex circuits.
Circuit Board Simulator:
Although circuit board simulators make it easy to develop a large circuit, they have some problems in the simulation process. Process variations occur when the design is generated, but circuit simulators do not consider these variations. Although the variations are minor, they can significantly affect the output.

Conclusion:
Computer simulation software is used to simulate and analyze the circuit, which saves time. It can process a large amount of experimental data from the natural output waveform, which is a perfect application for the analysis and design of the actual circuit. By using this software, students are motivated to learn with interest and enthusiasm. Before performing specific experiments, it can simulate them first.
If the design function is irregular or unreasonable, it can be quickly and repeatedly modified on the computer until it is correct. In this way, before the experiment, there is a specific understanding of the experimental results to have a broader understanding of the experiment so that it can achieve the benefit of the experiment and the future of society.
