Reading this article will take about 3 minutes. The previous article introduced the Arduino digital I/O pins and related functions, lighting up the onboard LED. This article will use a breadboard to build a circuit, allowing multiple LEDs to create a flowing effect. 1. Experimental Materials Uno R3 Development Board USB Data Cable Breadboard and … Read more
1. Hardware Preparation You’ll need an Arduino development board (such as Arduino Uno) and several LED lights. Connect the anode (long leg) of the LED lights through a current-limiting resistor (usually a few hundred ohms, such as 220Ω, to prevent excessive current from damaging the LEDs) to the digital pins of the Arduino board (for … Read more
☞ Essential Resources for Programmers to Advance to Architects, Free Giveaway ☜ The Raspberry Pi does not come with a display by default. If you want to view some system information, you need to log into the Raspberry Pi from a computer or connect an external monitor via HDMI. This can be a bit cumbersome, … Read more
Recently, I have been quite busy with work, but I still managed to squeeze out some time to finish the matrix LED clock mentioned in my last article. I made a video to introduce this clock, which you can watch on Bilibili or YouTube. Today, I am writing another article to detail the design concept … Read more
Key Points:Apple has adopted Mini LED backlighting in its high-end IT products, including the iPad Pro and MacBook Pro models. At the same time, Apple is considering using OLED displays for its next generation of high-end IT models. It is estimated that the manufacturing cost of OLED is significantly lower than that of Mini LED. … Read more
LCD: Backlight source emits light + liquid crystal color display, now using LED lights for backlighting. QD-LCD (Quantum Dot TV): The screen of a typical LCD TV uses LED backlight to emit blue light, which is converted into red, green, and blue light through phosphors, ultimately forming white light that is displayed on the liquid … Read more
With the continuous expansion of the 10.5 generation LCD and 6th generation flexible AMOLED production lines, the application of touch screens has also been continuously expanded. Currently, display panels are showing two major development trends: one is ultra-large size, and the other is curved and foldable. These two major trends have raised new requirements for … Read more
Current displays are typically used solely for information display, but they can integrate a range of different sensors for functionalities such as touch control, ambient light sensing, and fingerprint sensing. Light-responsive LEDs can display information and respond to light excitation, making them suitable for the development of future ultra-thin and large screens with a body-to-screen … Read more
