ARDUINO LCD KEYPAD SHIELD FOR ARDUINO IN PAKISTAN
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."
