The 16x2 Keypad LCD Shield is a solution for Arduino enthusiasts who want to work with an LCD and an Arduino without the need for external switches. There will be 6 momentary push buttons and a 2x16 LCD display. The LCD is interfaced with pins 4, 5, 6, 7, 8, 9, and 10. To detect the five pushbuttons, just Analog Pin 0 is used. Contrast adjustment and back-lit on/off controls are available on the LCD shield. It also exposes five analogue pins which can be used to connect and show analogue sensors. There is also an on-board power LED.
This design is wonderful since it allows you to simply connect sensors to the remaining pins and utilise it for monitoring or menu selection using the push buttons, as well as gaming. Testing and debugging are frequently required for project applications. When a computer is not available, displaying information immediately can be useful. If you're building something that won't be connected to a computer and want to see what's going on before putting it in place, this feature will come in handy to ensure the software runs smoothly.
On the top side of the board, the used LCD pins are hidden, making just the unused ones exposed. Conflicts with LCD pins on the top of the device will no longer occur.
