This program uses ADC0809 to collect the voltage output from RW2 and displays it on a seven-segment display. Now I want to write the displayed data to SBUF and send it to a PC. I have tried many times...
When an AC voltage is applied to a capacitor, the capacitor should have a charging and discharging process, and the voltage across the two ends should not change suddenly. This is also the principle o...
[color=rgb(34, 34, 34)][font="]To understand the amplification effect of transistors, we can use a very common object in life as an analogy. Let's take the NPN transistor as an example. The PNP transi...
