Week 6 Electronics Design

This week I will start studying electronic design, which will be another great challenge for me, learning to draw a circuit board through video tutorials, designing an embedded microcontroller to use sound to control lights, which is really interesting.

Learning Objectives

Group assignment:
- Use the test equipment in your lab to observe the operation of a microcontroller circuit board (as a minimum, you should demonstrate the use of a multimeter and oscilloscope)
Individual assignment:
- Select and use software for circuit board design
- Demonstrate workflows used in circuit board design

Group Assignment: Use the test equipment in your lab to observe the operation of a microcontroller circuit board

1 What is electronic design？

1.1 Introduction

It refers to the process of planning, designing and realizing the circuit and its components in the development of electronic products. It involves hardware design (such as circuit schematic design, PCB design) and software programming (if embedded systems are involved). It is a key link to transform theoretical knowledge into practical and usable electronic devices.

1.2 Design process

Stage	Description
Requirement Analysis	Identify product objectives and functional requirements, and provide lighting to facilitate nighttime operations.
Scheme Formulation	Select the right materials and determine the design cost.
Schematic Design	Use EDA software (such as KiCad, Eagle) to draw circuit schematics, defining the electrical connections between components.
PCB Design	Complete PCB layout and routing in EDA software to ensure that both electrical performance and physical dimensions meet design specifications.
Prototype Fabrication	Utilize PCB manufacturing processes to produce physical circuit boards, proceed with component soldering and assembly to create a testable prototype.
Debugging and Optimization	Conduct functional and performance testing on the prototype, identify and resolve potential issues, optimize designs.
Production Preparation	Assemble the prototype according to the material and design.

2 EDA（Electronic Design Automation）

LC EDA is an online electronic design automation tool developed by a Shenzhen-based company specifically for circuit design and PCB design, providing a complete solution from schematic design to PCB layout. It is cloud-based, with a rich component library, powerful simulation capabilities, and integrated PCB design and manufacturing services to support team collaboration and resource sharing.
