This is an astable waveform oscillator circuit I saw in a document. The circuit diagram is shown in Figure 1. The author said the waveform is shown in Figure 2, but I can't figure out why Vbe1 will ha
An abnormal picture is as follows:Original picture:Note: The original picture is 24-bit true color, and the display on the LCD is 565. The same 240*320
After I eliminated the short circuit fault, I found that it shut down automatically when the power was turned on. Later, the detection resistor burned, and it was very obvious that it was red and hot.
Ferrite beads are a type of anti-interference component that is currently developing rapidly. They are cheap, easy to use, and have a significant effect in filtering out high-frequency noise. [52RD.co
