I didn't find the right tools to disassemble it, and I tried a few times with a utility knife but couldn't open it. I won't post photos of the disassembly. There are disassembly posts on the Internet....
[hide] 1. The power cord of the metal casing is generally connected to the ground (FG) of the casing. It must be reliably grounded to ensure safety. Do not mistakenly connect the casing to the neutral...
As the title says, I have consulted LED driver chips, and they said that it can only be achieved by simulating PWM signals with a single-chip microcomputer.
I am new to microcontrollers.
Could you ple...
