LCD Keypad Kit for Raspberry Pi

Let's talk about LCD Keypads: everyone loves them and everyone can find a use for them but they seem to be limited to the Arduino field. What about the Raspberry Pi? Our friends over at Adafruit have come up a really nice LCD Keypad Kit for the Raspberry Pi that can be easily assembled and start being used as soon as you are done soldering it together! With this kit you will be able to easily control a 16x2 character White on Blue LCDthree backlight pinsand five different buttons using only two I 2 C pins from the Raspberry Pi. The LCD Keypad for Raspberry Pi consists of a 16x2white characterblue backlight LCD with a keypad consisting of 5 keys selectuprightdown and left. To save the digital IO pinsthe keypad utilizes the resourcefulness of the MCP23017 I/O expander IC which uses only two I 2 C pins and in return provides 16 general purpose pins. Since this is a kit some soldering and assembly will be required before use but once complete you will have a fully functioning LCD Keypad that can be plugged into your Raspberry Pi and start being used right away. Note: This is the blue and white LCD Keypad kit so you will need to break off a piece of 16 pin header from the stick in the kit and leave the two rightmost pads empty.
