32
-- Note: The resistor in series between pin 1 and pin 2 can be used for frequency adjustment. Since the layout of the PCB may cause overall frequency deviation, the frequency can be modified to the operating frequency of 108KHz by modifying its resistance value.
33
-- Since the chip operating frequency requires high precision, the stability and consistency of the input voltage must be ensured.
34
-- Changes in the power supply voltage will cause changes in the chip's operating frequency, thereby affecting the working effect of the atomizer.
35
-- The frequency error of the chip mainly comes from the oscillation resistor, so try to use a resistor with a precision of 1% to reduce the frequency deviation.
36
-- And when laying out the board, the oscillation resistors should be laid out strictly according to the anti-interference drawing method. The resistors should be placed as close to the pins of the chip as possible to reduce the resistance brought by the PCB board and the frequency changes caused by environmental interference.

+## TRIAC
6
+A TRIAC is a bidirectional, three-electrode AC switch that allows electrons to flow in either direction.
7
+It is the equivalent of two SCRs connected in a reverse-parallel arrangement with gates connected to each other. A TRIAC is triggered into conduction in both directions by a gate signal like that of an SCR.
8
+
9
+## SCR
10
+
11
+SCR stands for Silicon Controlled Rectifier. It is a three-terminal device that is used to control the flow of current.
