Unfortunately, these LCDs do require quite a few digital pins, 6 to control the LCD and then perhaps another 3 to control the RGB backlight for a total of 9 pins. That's half of the pins available on a classic Arduino!\u003cbr\u003e\u003cbr\u003eWith this in mind, we wanted to make it easier for people to get these LCD into their projects so we devised a shield that lets you control \u003cstrong\u003ea 16x2 Character LCD, up to 3 backlight pins AND 5 keypad pins using only the two I2C pins on the Arduino!\u003c\/strong\u003e The best part is you don't really lose those two pins either, since you can stick i2c-based sensors, RTCs, etc and have them share the I2C bus. This is a super slick way to add a display without all the wiring hassle.\u003cbr\u003e\u003cbr\u003eThis shield is perfect for when you want to build a stand-alone project with its own user interface. The 4 directional buttons plus select button allows basic control without having to attach a bulky computer.\u003cbr\u003e\u003cbr\u003eThe shield is designed for 'classic' Arduinos such as the Uno, Duemilanove, Diecimilla, etc. It will also work perfectly with Arduino Mega R3's. Earlier Mega's have the I2C pins in a different location and will require you to solder two wires from the I2C pins on the shield and plug them into the different I2C locations at Digital 20 \u0026amp; 21. This shield will not fit easily on top of an Arduino Ethernet because of the Ethernet jack height. You can use a set of stacking headers to give the shield more 'lift' above the jack.\u003cbr\u003e\u003cbr\u003eThis shield comes as a kit! Included is a high quality, USA-made PCB and all the components (buttons, header etc). \u003cstrong\u003eAn LCD is not included, you will need to order one of our fine 16x2 Character LCDs\u003c\/strong\u003e - just pick up whichever style you like the most (blue \u0026amp; white, RGB negative or RGB positive).\u003cbr\u003e\u003cbr\u003eThis kit has only been tested with the LCDs we sell and support, if you use another we will not be able to guarantee it works and we will not be able to troubleshot or support it!\u003cbr\u003e\u003cbr\u003eAssembly is easy, even if you've never soldered before and the kit can be completed in 30 minutes. Check the product tutorial page for assembly instructions before purchasing\u003cbr\u003e\u003cbr\u003eIf you don't already have an LCD we suggest picking up a 'pack' which includes the LCD and will save you a bundle: RGB Positive Pack, RGB Negative Pack and Basic Blue\u0026amp;White Pack.\u003cbr\u003e\u003cbr\u003eOf course, we even wrote an easy-to-use Arduino library that you can easily add to your project. It acts just like the built in LiquidCrystal library, but automatically uses the shield pins. You can also easily query the 5 keypad buttons to get input through the library, so you get extra buttons without using any more pins.\u003cbr\u003e\u003cbr\u003eAt this time, the library and shield can control the RGB backlight of our character LCDs by turning each LED on or off. This means you can display the following colors: Red, Yellow, Green, Teal, Blue, Violet, White and all off. There is no support for PWM control of the backlight at this time, so if you need to have more granular control of the RGB backlight to display a larger range of colors, this shield can't do that (the I2C expander does not have PWM output).\u003cbr\u003e\u003cbr\u003eProduct page with tutorials, documentation and assembly information\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e \u003cdiv class=\"row\"\u003e \u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\u003cul\u003e\n\u003cli\u003eEagleCAD PCB files and Fritzing available in the product tutorial\u003c\/li\u003e\n\u003cli\u003eDimensions: 2.1\" x 3.2\"\u003c\/li\u003e\n\u003cli\u003eFor use with 16x2 Character displays\u003c\/li\u003e\n\u003cli\u003ePlug and play with any Arduino 'classic' - UNO, duemilanove, diecimilla, etc as well as Arduino Mega R3.\u003c\/li\u003e\n\u003cli\u003eUses only the I2C pins - Analog 4 \u0026amp; 5 on classic Arduinos, Digital 20 and 21 on Arduino Mega R3\u003c\/li\u003e\n\u003cli\u003eThis board\/chip uses I2C 7-bit address 0x20\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e \u003c\/div\u003e\n\u003cul id=\"product-files\"\u003e \u003c\/ul\u003e \u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e \u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":48620786942174,"sku":"bps1787257410046","price":6.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0745\/0705\/9422\/files\/adafruit-i2c-controlled-keypad-shield-kit-for-16x2-lcd_1.jpg?v=1787257419"},{"product_id":"featherwing-tripler-mini-kit-prototyping-add-on-for-feathers","title":"FeatherWing Tripler Mini Kit - Prototyping Add-on For Feathers","description":"\u003cp\u003eThis is the \u003cstrong\u003eFeatherWing Tripler \u003c\/strong\u003e- a prototyping add-on and more for all Feather boards.
