Description of the high and low trigger, friends do not understand Take a look at:<\/p>\n
\u00a0<\/p>\n
High level trigger is a trigger voltage between the signal input and ground can be understood as a way of the signal input terminal and VCC cathode short trigger;<\/p>\n
\u00a0<\/p>\n
Low trigger means is the voltage between the signal input terminal and the ground for the OV trigger mode can be understood as a way of the signal input terminal and GND negative short trigger<\/p>\n<\/body>","protected":false},"excerpt":{"rendered":"
