        The street light system based on ZigBee technology and LED light source is a highly automated, energy-efficient urban lighting system. LED light source is a new type of lighting source that is efficient, environmentally friendly, safe and durable. Wireless control technology can scientifically and efficiently c

　　An LED (light emitting diode) is a semiconductor diode (a pn junction) that emits light when positive current flows from the anode to the cathode of the LED. The anode is represented by "+", which is the positive pole of the diode. The cathode is represented by "-", which is the negative pole of the diode. 　　Q: How

Shanghai, China, August 9, 2021 - ViewSonic announced the launch of the R3, a 1080p Full HD smart portable LED projector. The ultra-light and portable new R3 has a color gamut coverage of more than 100% of the Rec.709 standard and a Full HD resolution of 1920x1080, providing users with a full HD, true color restorat

Buttons and displays are the basic input and output components of a single-chip microcomputer system. The following introduces a general instrument panel consisting of a 6-digit digital tube driven by 74LS164 and 4 buttons. The schematic diagram is shown below script src="/gg/article-main.js" /script script

1. LED structure Generally speaking, it is a square diode chip mounted in a special epoxy layer of a plastic, resin or ceramic base. The electrons in the center of the semiconductor can be converted to generate light through the sensing material, and the microchip sealed in the "hood-shaped" epoxy layer can "map" t

1. Experimental task 　　As shown in Figure 13, use the P0 port P0.0-P0.7 of the AT89S51 microcontroller to connect to the a-h segments of a common cathode digital tube , and the common end of the digital tube is grounded. The digital tube displays 0-9 numbers in a cycle, with a time interval of 0.2 seconds. 2. Circuit

Everything has a process of occurrence, development and extinction, and LED is no exception. It has a certain lifespan. Early LEDs were just gifts such as flashlights and table lamps. They were not used for a long time, and the lifespan problem was not prominent. But now LEDs have begun to be widely used in o
