Simple temperature alarm circuit

I haven't figured it out yet. I'll start with something simple, like a basic teaching board. In fact, it's barely even a complete verification board. It's based on the temperature alarm circuit in the Electronic Technology Circuit Design Tutorial, which has been greatly simplified. It has removed the possible microcontroller control interface and some unnecessary extra content (digital tube display).
The core component is the temperature alarm module shown in the image below. The resistance value is calculated using the following formula:
Voltage V+ at the non-inverting terminal = Sliding resistor / Sliding resistor + Pull-up resistor
; Voltage V- at the inverting terminal = Thermistor / Thermistor + Pull-up resistor.
The detailed calculation process is shown in the video. I chose a 1kΩ resistor because this is just a test board and doesn't need to achieve precise functionality. Testing only requires placing a soldering iron on the thermistor to reach the desired temperature. To ensure normalization, I chose a similar resistance value (the same as the LED current-limiting resistor).
Other components won't be explained in detail for now because I don't think anyone would actually replicate this XD. The video content provides a basic explanation of the functions. For this experiment, I suggest freely modifying the values, packages, and models of many electronic components to deepen your understanding. This depends on the components you have on hand. These are the components I have, so I haven't checked if the BOM selection is completely reasonable, but it's generally correct. (Complete demonstration video, digital circuit project collection)
