In this Arduino LCD tutorial, we will learn how to connect an LCD (Liquid Crystal Display) to the Arduino board. LCDs are very popular and widely used in electronics projects for displaying information. There are many types of LCD. This tutorial takes LCD 16x2 (16 columns and 2 rows) as an example. The other LCDs are similar. โ€ป NOTE THAT:

The Arduino LiquidCrystal and Keypad library is used for displaying the status and detecting key press. The LCD displays the "KEYPAD LCD TEST" as welcome screen at the first line Number of seconds since start "SEC= 123" is displayed at the second line column one. The detected key is displayed at ("KEY= 5") second line column 9 on wards. /*

4ร—4 Keypad Interfacing With Arduino Uno. To connect the 4ร—4 keypad to Arduino, you need to interface 4-row pins in the keypad which are (R1, R2, R3, R4) with the Arduino digital pins (9, 8, 7, 6), and the 4-column pins which are (C1, C2, C3, C4) with Arduino digital pins (5, 4, 3, 2). The picture down below shows the connection in detail.
