Problem description:
1. The designed buzzer drive circuit is shown below. The resistor in the figure was later changed to 470Ω, but the problem was still not solved;
2. The buzzer is an active buzzer;
I recently used the LM2596 chip to draw a power module, 20V DC input, connected a 25V100uF tantalum filter capacitor at the input end, connected to the load, the total current of the circuit was about

1. I didn't submit the previous video, so I'm submitting a small video now, which shows the experimental results of the low-voltage part. The code is only partially available now.attach://383510.mp4 T
I want to use an operational amplifier to measure the voltage difference between the two ends of the capacitor to be measured (the voltage difference is between 0-16V), and then reduce the value to (b
