mini touch light

Overview

Use the SGL8022W chip removed from the charging desk lamp. For details on its functions, see the reference manual in the attachment.
It has no practical value and is only for fun.
You can consider adding a small-value current-limiting resistor to the LED string to increase battery life, but I will not change it here.
There are four modes that can be selected with a toggle switch, and dimming can be achieved by touching the touchpad on the PCB.
