Touch dimmable desk lamp with clock

Overview

LED desk lamp based on 51 microcontroller, powered by TYPE-C, can be connected to a power bank to work. Touch button dimming, 4 levels of brightness. The LCD displays the time, and the real-time clock does not stop when the power is off.
This is a low-cost and practical design, not difficult, suitable for learning microcontroller production.
The STC8G1K08 microcontroller is used as the main control, the resistor voltage divider drives the segmented LCD, and the ADC performs the touch button function. TMI5102 drives LED with a maximum current of 2A.

Why doesn't the potentiometer have voltage?
[p=24, null, left][color=#333333][font=arial, 宋体, sans-serif,]As shown in the figure, R10 is a potentiometer. Now, by changing the resistance value of R10, the voltage input to the comparator changes.
