The product consists of an \u003c\/span\u003e\u003cstrong\u003eAtmega328\u003c\/strong\u003e\u003cspan\u003e microcontroller, 4 x \u003c\/span\u003e\u003cstrong\u003eBC847\u003c\/strong\u003e\u003cspan\u003e NPN transistors to drive the common cathode displays. All displays are used in multiplexing configurations. The circuit operates with \u003c\/span\u003e\u003cstrong\u003e5V DC\u003c\/strong\u003e\u003cspan\u003e and consumes a few milliamps. Arduino code is provided to test the board. The code is pretty simple, it will read 0 to 5V on analog pin \u003c\/span\u003e\u003cstrong\u003eA0\u003c\/strong\u003e\u003cspan\u003e and display 0 to 1000 display, basically 0 to 5V mapping to 0-1000. Users may write their own code to read an analog voltage from a sensor or other source and display it on the 4 x 7segment displays.\u003c\/span\u003e\u003c\/p\u003e","brand":"dotfry","offers":[{"title":"Default Title","offer_id":47222985228460,"sku":"C114","price":18.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/6436\/7532\/files\/C114.jpg?v=1789561421","url":"https:\/\/dotfry.com\/products\/arduino-4-digit-0-5-common-cathode-7-segment-display-module","provider":"dotfry","version":"1.0","type":"link"}
