Embedded Development Basics: Analog Circuits

This course covers the core knowledge of analog circuits. It uses a combination of theory and practice to help students understand common components and packages, learn the internal working principles of the NE555 chip, and draw analog circuits based on NE555 by themselves, so as to help students quickly master analog circuits.
