User Interface Shield from rhydoLABZ makes it easy to use a 16x2 Alphanumeric Display with your Arduino. We have devised this shield to let you control a 16x2 Character LCD along with 5 keypad pins and few other added features. This shield is perfect 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.

The alphanumeric LCDs do require quite a few digital pins,  to control and communicate with the LCD. That has its cost when it comes to a classic Arduino, here we have the solution! Our shield uses 4bit mode of interfacing, added advantage, works perfectly in 4-bit mode with the “LiquidCrystal” library found in the Arduino IDE, using this library will allow you to control the LCD with only 6 digital I/O lines.

Apart from the display interfacing, it has input switches, on board buzzer and LEDs. Shield uses the digital pins D8 to D13 for LCD interfacing, D3 toD7 for keypad buttons and D2 for buzzer. Analog pins A2, A3 and A4 are connected with LEDs, A0 comes in connection with a preset; put to use the ADC functionality. A
trimmer resistor is employed to control the LCD contrast. Arduino reset switch is brought out on the shied for easy accessibility.

This product comes as a kit! Includes high quality PTH PCB, 16x2  alphanumeric LCD and onboard components (buttons, buzzer, header etc). Screws and spacers are provided along for ease of assembly. Most of the connections are jumper selective which makes it apt for prototyping as well. The shield can also be configured to support micro OLEDs with an add on berg strip. Ultimately rhydoLABZ UI shield is the super slick way to add a display without all the wiring hassle on your Arduino.

Working with an arduino & LCD module was always a challenge for me. I always mess up the wiring. Now it is as simple as just plugging in this shield. Love you. _3
