Function introduction: 1. 60 lamp beads represent 60 seconds, and I wrote 5 animations Built in. 2. The photoresistor is located at the center of the front of the clock and senses external light to adjust its own brightness. 3. The time display and temperature display are separated, and the time display is displayed in a cycle every time it is turned on. 4. The temperature sensor is ds18b20. This temperature is still more accurate than some clocks sold online that use temperature-sensitive resistors as temperature sensors. 5. Comes with ds1302 and a battery, running time when power is off 6. Built-in 3 buttons for debugging 7. A buzzer, used as an alarm speaker 8. Microcontroller STC8A series, 44 pins

High power switching power supply failure
I encountered several 27V switching power supply failures. One was that the switching power supply sparked during operation. Then when I turned it on again, there was no output. The fan was running no
A weak question about semiconductors
The textbook says that the formation of PN junction is caused by the mutual diffusion and recombination of majority carriers. What I don't understand is how the holes in the P region "diffuse" to the
Are there instructions for using the oscilloscope?
Does anyone have instructions for using an oscilloscope? Beginners generally don't know much about this stuff, so please share.
Question + Ask for large screen LCD screen recommendation
Dear experts, please recommend a large LCD screen, just for display, or a touch screen. I don't have any experience, please provide system information, thank you
The spring breeze is not as good as you, the most beautiful confession is for you~
On this day when even the air is pink, This IC editor has also decided to change the style, Let's put aside the technical solution for now. Thinking of taking this opportunity, To those who have alway
Three-phase asynchronous motor as position loop control
There is an incremental encoder on the reducer shaft of the three-phase asynchronous motor. The encoder output is connected to the encoder board of the frequency converter and to the input of the PLC
