GND GND is the negative input port of the power supply. OUT OUT is the signal output port, which is connected to the I\/O port of the single-chip microcomputer. Generally, it is connected to an external interrupt.\u003c\/li\u003e\n\u003cli\u003eFor other main control boards or higher-level main control boards (such as Arm), if you need to set the I\/O port to input\/output mode, you must set it to input mode\/receive mode, otherwise it cannot be used. 51 series MCU can be used directly, no need to set input and output mode\u003c\/li\u003e\n\u003cli\u003eNote: For Arduino players should set the MCU's I\/O port to input mode\/receive mode, otherwise it cannot be used.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOverview\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Teyleten Robot\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Weight:\u003c\/strong\u003e 0.02 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle:\u003c\/strong\u003e Modern\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Supply Voltage:\u003c\/strong\u003e 5 volts\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Teyleten Robot","offers":[{"title":"Default Title","offer_id":52156158968096,"sku":"B08977QFK5","price":16.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1006\/7682\/9472\/files\/41QV7nhyttL.jpg?v=1786018450","url":"https:\/\/tinyracer.com\/products\/teyleten-robot-ir-infrared-slotted-optical-optocoupler-module-speed-measuring-sensor-3-3v-to-5v-photo-interrupter-sensor-for-arduino-10pcs","provider":"TinyRacer","version":"1.0","type":"link"}
