Original work LED meteor shower lamp (51 single chip microcomputer program code) product sharing!-EEWORLD

Collect

Recently, our company has produced a meteor shower lamp! Now we share it with you!

1. Picture sharing:

2. PCB file sharing:

3. Schematic diagram sharing:

Four,

There are only 5 light tubes made above. If you need to add more light tubes, just slightly change the following program. If you increase
the number of light tubes and arrange the light tubes in a circle or square, the effect will be quite awesome.

This meteor lamp has a diameter of only 1.5 cm and can only be made into 30 cm, 50 cm, 80 cm, 1000 cm, etc.
This thing is mainly for decoration. Technical support: http://www.51hei.com/ All source codes are open below.
Please give us your advice. You can modify the program code at will, but it cannot be used for commercial purposes.

/*Meteor Shower Program Code Author: Hu Qin 2011-12-12
Single Chip Microcomputer Model: STC11F04 IO Ports 16! Principle:
Use PWM to simulate meteor shower: divide the brightness level into 8 levels
, and achieve the meteor shower effect by changing the brightness of each group of LEDs.
(Because the meteor shower is bright at the front and gets darker at the back, just like a dragon, dragging its tail over),

Three steps to calculate the installation cost of LED light strip project

LED light strips are mainly used for decoration. Since many customers are not very familiar with them, they often miss some links when calculating the project quotation, which adds unnecessary costs to themselves. Here is how to calculate the project installation cost of light strips. 1. Number of light strips Calcu

Analysis of the principle of improving the internal quantum and electro-optical conversion efficiency of LED

　　When a forward voltage is applied to the PN junction of an LED , current will flow through the PN junction, and electrons and holes will recombine in the PN junction transition layer to generate photons. However, not every pair of electrons and holes will generate photons. Since the PN junction is an impurity semi
