LCD KeyPad Shield 16X2 Blue


৳ 330.00

The LCD Keypad shield is developed for Arduino compatible boards, to provide a user-friendly interface that allows users to go through the menu, make selections etc. It consists of a 1602 white character blue backlight LCD. The keypad consists of 5 keys — select, up, right, down and left. To save the digital IO pins, the keypad interface uses only one ADC channel. The key value is read through a 5 stage voltage divider.

Note: Version 1.1 main updates are the button values, which have being updated on the example code. For older version check the comments and edit, or use the Enhanced V1.0 library .
