This DFRobot LCD Keypad Shield (male pin connector) for Arduino comprises a 16x2 blue LCD display and 6 momentary pushbuttons, from left to right, SELECT, LEFT, UP, DOWN, RIGHT and RESET. The shield can be directly plugged onto an Arduino Duemilanove board, making soldering or fly-wiring for connection unnecessary. Pins and 9 are used as the interface to the LCD. The shield operates at 5V. Main features include: -A 16x2 blue LCD -Adjustable contrast -Laminated design and easy to expand -Using modified LCD4Bit Interface Modified LCD4Bit Interface: In order to preserve the SPI port for future use, the Digital IO pins DB7-10 and pin11& pin 12 used in the original LCD4Bit library have been moved to DB4-7 and pin 8 & pin 9 respectively. Keypad: The keypad consists of 5 pushbuttons — SELECT, LEFT, UP, DOWN and RIGHT plus a RESET button. To save the digital IO pin resource, the keypad interface only uses one ADC channel. The key value is read through a 5 stage resistor voltage divider. When a key is pressed, the ADC reads the voltage value through the voltage divider; then the voltage value is compared to the voltage value threshold stored in an array to identify which key has been pressed."

The Arduino Pro Mini is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 8 analog inputs, an on-board resonator, a reset button, and holes for mounting pin headers. A six pin header can be connected to an FTDI cable or Sparkfun breakout board to provide USB power and communication to the board. The Arduino Pro Mini is intended for semi-permanent installation in objects or exhibitions. The board comes without pre-mounted headers, allowing the use of various types of connectors or direct soldering of wires. The pin layout is compatible with the Arduino Mini.
