Arduino 16X2 LCD Keypad Shield

16X2 LCD Keypad Shield for Arduino

The LCD keypad shield is suited for Arduino UNO board and Leonardo Board compatible with Arduino. The blue LCD Keypad Shield is sometimes called a navigation shield because it comes with 6 momentary push buttons for menu navigation. Besides the push button, it also includes a 2×16 LCD.

This is a very popular LCD Keypad shield compatible with Arduino and other variants. It includes a 2×16 LCD display and 6 momentary push buttons. Pins 4, 5, 6, 7, 8, 9, and 10 are used to interface with the LCD. The onboard LED indicates power on.

The 16 x 2 LCD shield is a great solution for an embedded systems engineer who wants to use an LCD module while plugged onto the Arduino. The 16 x 2 LCD module has a great design and is under friendly. It easily lets you keep connecting sensors to the rest of the pins, and use it for monitoring or menu selection with the push buttons even for gaming.

Why is the 16 x 2 LCD Keypad shield necessary?

As an embedded systems engineer, if you are planning to build a project which is not attached to a computer and you need to check what is going on when you place it on position, this addition will prove very valuable to make sure the program is running well.
