The most beautiful electronic design is probably the LED series, especially the Guangzhou Tower design, the LED series test is not only technical, but also tests the ability and patience. I have organized 8 LED boutique projects on the Circuit City, there is a Guangzhou Tower, let's learn together.
1,8x8x8 optical cube circuit solution (PCB + schematic + program)
Four Buttons Features:
1, K1 button: enter mode selection, day night mode control
2, K2 key: enter 3D8 host mode (press K1 button first after power on)
3, K3 key: enter 42 kinds of offline animation mode (press K1 button first after boot)
4, K4 button: enter 14 kinds of offline audio mode (to press the K1 button first after boot)

2, 51 microcontroller's infrared remote control control two LED lamp design - (Schematic + program)
I have to do an infrared remote control to control the brightness of the two incandescent lamps, a receiving circuit for transmitting circuitry, using a single chip microcomputer:
There are two knob buttons on the transmit circuit, which can nozzle two highlight LED lamps, and cannot be influential, there are two buttons, and the two lights will become a full-brightness state, and the other is changed. There must be an AD conversion circuit.

3. Intelligent table lamp based on atmegal16 microcontroller - highlight LED-photosensitive - hot release infrared - (Schematic + program source code)
This design is made by AVR16 single-chip circuit + highlight LED lighting circuit + button circuit + Direction switch circuit + photosensitive resistance circuit + hot release infrared module circuit + LED indicator circuit + power circuit composite.
1, the table lamp can be powered by a battery 4, or power supply via a USB line (5V).
2, the table lamp has two modes of manual mode and automatic mode. By the dial switch, two modes are selected, and the switch is turned on, it is manual mode, and automatically moderates. Dial, and the yellow indicator light is on, dial, yellow indicator.
3. In manual mode, you can control the brightness and brightness of the highlight LED light by pressing the button, and the brightness is divided into 3 files.
4, in automatic mode, detect light by photosensitive resistance, and automatically control the brightness of the highlight LED lamp, the brightness level is 0 (not bright), low, medium, and high. In automatic mode, it can be automatically turned off when the user leaves the lamp detection range after 10 seconds. The user is detected by the hot release infrared module to detect whether the user leaves the lamp detection range.

4. Music reactive multicolor LED light board based on Arduino sound detection sensor and 12V adapter design
Music reactive multicolor LED lamp project. In this project, a simple 5050 RGB LED light strip is used (not addressed LED WS2812), an Arduino sound detecting sensor and a 12V adapter.
So how do it work? If you carefully check the Arduino IDE source code of the project, the threshold (like 0 to 1023) is defined, analog value from the Arduino sound sensor (varying the strength of the music). ), If the value of the sound sensor does not match the threshold, the Arduino Random () function will be activated. To create 6 different color groups in a random function, you can create different color combinations by changing values in these color groups. If there is no analog value from the sound sensor, the function will stop.

5. Rotating LED electronic clock based on STC15, display brightness according to the environment light adjustment (circuit diagram + source + BOM table)
Rotate the LED Electron Clock; use the STC15W408AS microcontroller and the DS1302 clock chip, 60 LEDs can be converted into a variety of styles, while the temperature can be displayed, and the brightness is displayed based on the ambient light.

6, LED Matrix Clock Dot Staver Clock
5 digits 8x8 dot clocks, using the 5x7 font. It is just that the timestock can be displayed.
1, master: STM32F411CEU6;
2, RTC: DS3231
3, dot matrix drive: HT16D35, brightness adjustable, with 64 gradation, constant current drive;
4, right: ESP8266 automatic timing

8, Guangzhou Tower DIY upgrade, color LED display, support infrared remote control
The LED tower is imitated from Guangzhou Tower. Guangzhou Tower is also known as Guangzhou New TV Tower, nicknamed Xiao Yao. It is the highest building in Guangzhou, the design of the tower is very characteristic, especially at night under light, it is beautiful. We use STC12C5A60S2 as a control system, the display portion is 16 × 16 o'clock, and through the production of Guangzhou Tower, it can better enhance the principle of the single-chip display.
