The LED1 is the corresponding indicator light strip 31 in FIG. 2 . The principle used is the monostable working mode of IC555. This circuit is a conventional touch switch circuit, and this circuit is often used in the light touch switch on the corridor. Usually IC555 is in monostable mode, 3 bits of output are low, LED1 is off; when human hands or other conductors touch the metal cap 21 in Figure 2, the induction signal of the human body passes through capacitor C1 to trigger terminal 2 of IC555, Trigger the setting of IC555 which is in monostable state, make the 3rd pin of IC555 output high level, drive LED1 to light up, that is, the indicator light band 31 lights up, and at the same time output high level to the second I/O terminal of the single-chip microcomputer, Indicates that a hand or other conductor has touched the metal cap 21 .
