It can used in many applications that require 2-digit display and switches inputs. Possible application of this board is a 2-digit counter, 2-digit countdown timer, token display, score board etc. 2 x 7 segment 0.56-inch Common cathode displays are used in multiplexing mode. Refer to the connection table to check connections between display segments and Atmega328 chip. A led connected to A4 pin of IC is used as indicator LED. All 3 switches have pull-up resistors of 10Kohms, 220E ohms series resistors used between I\/O pin of Atmega328 chip and display segments.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003eOperating Power Supply VCC 5V DC @ 50mA (CN1)\u003cbr\u003e3 Tactile Switches with pull up resistors\u003cbr\u003eA LED on A4 pin for function\u003cbr\u003eExample code provided below so you can test the board. it is 99 second count down timer with adjustable time 00 to 99 Seconds.\u003c\/p\u003e","brand":"dotfry","offers":[{"title":"Default Title","offer_id":47182734950572,"sku":"B109","price":18.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/6436\/7532\/files\/B109A.jpg?v=1789100105","url":"https:\/\/dotfry.com\/products\/arduino-compatible-2-digit-7-segment-display-board-for-timer-counter","provider":"dotfry","version":"1.0","type":"link"}
