After powering on the chip, the voltage of each power pin is normal, but the waveform of the crystal pin cannot be seen with an oscilloscope. The voltage of both crystal pins is about 0.8V, and the wa...
The resistor parallel circuit is the most basic parallel circuit. All responsible circuits can be converted into resistor series and resistor parallel circuits to understand the working principle. The...
The small speaker is great! I took a few photos of it right after I got it!

There will be flashing lights when in use!!
There are also clocks and alarm clocks!
Very good! Keep up the good work!!...
