It includes a 2×16 LCD display and 6 momentary push buttons. Pins 4, 5, 6, 7, 8, 9 and 10 are used to interface with the LCD. Just one Analog Pin 0 is used to read the five pushbuttons. The LCD shield supports contrast adjustment and back-lit on\/off functions. It also exposes five analog pins for easy analog sensor plugging and display. An on board power LED is also provided.\u003c\/p\u003e\n\u003cp\u003eThis design is great since easily lets you keep connecting sensors to the rest of the pins, and use it for monitoring or menu selection with the push buttons even for gaming. Often project applications require testing or debugging. Displaying information right away help on most occasions when a computer is not at reach. If you are planning to build something not attached to a computer and you need to check what is going on when you place it on position, this addition will prove very valuable to make sure the program is running well.\u003c\/p\u003e\n\u003cp\u003eThe used LCD pins are not exposed on top side of the board leaving only the unused ones. This way, conflict with LCD pins on top of the board will not happen anymore.\u003c\/p\u003e\n\u003cp\u003eThe buttons are connected to only one analog input pin through resistors to give a different voltage for each button, thus saving on input\/output pins. Reading the buttons is easy and example code is shown below\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePin Connections:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePin                 Function\u003c\/p\u003e\n\u003cp\u003eAnalog 0 Buttons (select, up, right, down and left)\u003c\/p\u003e\n\u003cp\u003eDigital 4         DB4\u003c\/p\u003e\n\u003cp\u003eDigital 5         DB5\u003c\/p\u003e\n\u003cp\u003eDigital 6         DB6\u003c\/p\u003e\n\u003cp\u003eDigital 7        DB7\u003c\/p\u003e\n\u003cp\u003eDigital 8         RS (Data or Signal Display Selection)\u003c\/p\u003e\n\u003cp\u003eDigital 9         Enable\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures :\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe LCD Keypad shield is developed for Arduino compatible boards, to provide a user-friendly interface that allows users to go through the menu, make selections etc.\u003c\/li\u003e\n\u003cli\u003eIt consists of a 1602 white character blue backlight LCD.\u003c\/li\u003e\n\u003cli\u003eThe keypad consists of 6 keys select, up, right, down, left and reset.\u003c\/li\u003e\n\u003cli\u003eTo save the digital IO pins, the keypad interface only uses one ADC channel.\u003c\/li\u003e\n\u003cli\u003eThe key value is read out through a 5 stage voltage divider.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOperating Voltage: 5V\u003c\/li\u003e\n\u003cli\u003e5 Push buttons to supply a custom menu control panel\u003c\/li\u003e\n\u003cli\u003eRST button for resetting arduino program\u003c\/li\u003e\n\u003cli\u003eIntegrate a potentiometer for adjusting the backlight.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003ePin used:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eD4-D7    -\u0026gt; LCD Data transmission\u003c\/li\u003e\n\u003cli\u003eD8       -\u0026gt; Register Select\u003c\/li\u003e\n\u003cli\u003eD9       -\u0026gt; Enable pin\u003c\/li\u003e\n\u003cli\u003eD10      -\u0026gt; Backlight control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAPC\u0026amp;BT pin header for connecting wireless devices, directly compatible with:\u003c\/li\u003e\n\u003cli\u003eAPC220 Radio Communication Module\u003c\/li\u003e\n\u003cli\u003eExpanded available I\/O pins\u003c\/li\u003e\n\u003cli\u003eExpanded Analog Pinout with standard configuration for fast sensor extension\u003c\/li\u003e\n\u003cli\u003eDimension: 80 x 58 mm (3.15x 2.28 in)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003ePackage Includes :\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1 x 1602 LCD Keypad Shield Blue Backlight\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"eBhoot Electronics","offers":[{"title":"Default Title","offer_id":43465037348982,"sku":null,"price":170.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0697\/7345\/9574\/files\/Untitled_design_-_2022-09-25T130225.682_4dde7338-d770-4b64-b816-b250880b9a6a.png?v=1780229395","url":"https:\/\/ebhoot.com\/products\/1602-lcd-board-keypad-shield-blue-backlight-for-arduino","provider":"eBhoot Electronics","version":"1.0","type":"link"}
