Artificial Intelligence Artificial intelligence is a term that many are familiar with. When people mention it, they often do not consider its specific connotation, treating it more as a synonym for information technology education, especially programming education. However, the term artificial intelligence cannot comprehensively represent the current state of information technology education. Information technology education … Read more
This week, I will introduce you to a beautiful e-paper clock that also functions as a weather station (can automatically set via GPS). It can run for about 6 months on 4 AAA batteries, and to ensure safety and reliability, it does not require any network connection. Features include: Automatic setting (via GPS) Current temperature. … Read more
This experiment uses Arduino to directly drive the 1602 LCD to display text. The 1602 LCD is widely used in applications. The original 1602 LCD used the HD44780 controller, and now various manufacturers’ 1602 modules basically use compatible ICs, so their characteristics are generally consistent.1602LCD main technical parameters: Display capacity is 16×2 characters; Chip operating … Read more
