When the pressure is withdrawn, the switch is disconnected, and its internal structure is realized by the force change of the metal shrapnel. We can clearly find in the following four-pin circuit diagram that under normal circumstances, the 1 and 2, 3 and 4 pins of the key are connected; When we press the button, the four feet connect with each other; When the key is released, the normal state is restored. Key control can be realized by using digital I\/O. The meaning of digital I\/O port is INPUT and OUTPUT interfaces. Now let's try to use the INPUT function of I\/O in Arduino, that is, the function is to read output values from external devices in this experiment. We used buttons and LED lights to complete the experiment using INPUT and OUTPUT as a combination. Our key module outputs a low level when the key is pressed and a high level when the key is released.\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003cp\u003ePin name description\u003c\/p\u003e \u003cp\u003eG GND (Power input negative)\u003c\/p\u003e \u003cp\u003eV VCC (Power input positive)\u003c\/p\u003e \u003cp\u003e1 Digital signal pin\u003c\/p\u003e \u003cp\u003e2 Digital signal pins\u003c\/p\u003e \u003cp\u003e3 Digital signal pins\u003c\/p\u003e \u003cp\u003e4 Digital signal pins\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003cp\u003eModule parameter\u003c\/p\u003e \u003cp\u003eSupply voltage: 3.3V\/5V\u003c\/p\u003e \u003cp\u003eConnection mode: 2.54mm pin row\u003c\/p\u003e \u003cp\u003eInstallation method: Double screws fixed\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003cp\u003e\u003cimg referrerpolicy=\"no-referrer\" src=\"http:\/\/sc04.alicdn.com\/kf\/Hdd98e809b02845c79bd2172c8352c53c6\/221371796\/Hdd98e809b02845c79bd2172c8352c53c6.png\"\u003e\u003cimg referrerpolicy=\"no-referrer\" src=\"http:\/\/sc04.alicdn.com\/kf\/Hfd6bc731f61c422b83e256bc685502d69\/221371796\/Hfd6bc731f61c422b83e256bc685502d69.png\"\u003e\u003cimg referrerpolicy=\"no-referrer\" src=\"http:\/\/sc04.alicdn.com\/kf\/H0b95d91efa974624a7525451d8748ce8i\/221371796\/H0b95d91efa974624a7525451d8748ce8i.png\"\u003e\u003cimg referrerpolicy=\"no-referrer\" src=\"http:\/\/sc04.alicdn.com\/kf\/H118784369a3340c280eab22f0694ad684\/221371796\/H118784369a3340c280eab22f0694ad684.png\"\u003e\u003cimg referrerpolicy=\"no-referrer\" src=\"http:\/\/sc04.alicdn.com\/kf\/Hfd39d1e2d01043c19978be7e86015174P\/221371796\/Hfd39d1e2d01043c19978be7e86015174P.png\"\u003e\u003cimg referrerpolicy=\"no-referrer\" src=\"http:\/\/sc04.alicdn.com\/kf\/H42bcc6b69867459d94d72547b6b6dc70T\/221371796\/H42bcc6b69867459d94d72547b6b6dc70T.png\"\u003e\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003c\/div\u003e \u003c\/div\u003e Lonten is a manufacturer of electronic components, more than 20 years of PCB，PCBA production experience,welcome OEM Custom order.","brand":"Lonten Tech","offers":[{"title":"Default Title","offer_id":54098911035587,"sku":null,"price":0.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0659\/3416\/4163\/files\/Ha4d0a553a2484f77aeca3fa6cef99377Z.webp?v=1791625741","url":"https:\/\/lontentechnology.com\/products\/touch-four-button-switch-module-compatible-with-arduino-development-board-sensor-raspberry-pi-51-mcu-suite-customize","provider":"Lonten Tech","version":"1.0","type":"link"}
