Thx a lot for this Video, however the gain of the 2nd OpAmp should be A=-R2 / R1(1+SCR2), if the value of R1 and R2 are very close to each other, then they can be cancelled out.

No wonder how those people in NK got brainwashed so easily, just look at the comments on Youtube, so many people just believe whatever they see and hear from the video without using their brain.
Can't believe there are so many people would blame China for these unfortunate NK women.

About MrNingxiaoyu's channel
good explanations for H bridge, however, current value shown in your simulation 19mA would not be enough to drive any dc motor, you might need some value around 100mA to run it effectively.
These values shown might confuse newbies of electronics.
