1. Introduction 1.1 Project Development Background With the deep penetration of smart home technology and the rapid development of embedded microcontroller (MCU) technology, the application of large-scale integrated circuits in the consumer electronics field is becoming increasingly widespread. Home lighting devices are upgrading from “single lighting” to “smart adaptation and humanized services.” As a core … Read more
Click on the arrow“blue text”, and follow us! Photoresistor Also known as light-dependent resistor (LDR), it is a semiconductor resistor that is sensitive to light. Its core characteristic is quite interesting: the stronger the light, the lower the resistance; the weaker the light, the higher the resistance, functioning like an “electronic valve” that can automatically … Read more
