16*2 Character LCD Displays are most commonly used for open source Arduino projects, to display text and number information. The best way to interface Arduino microcontroller with LCD is in 4-bit mode. Common methods for connecting LCD directly connected displays and the connected through the I2C adapter. The I2C Method is more costly but needs only 4 wires to connect LCD to Arduino, which makes it very attractive and an easy-to-use option for Arduino projects.
Step 1 : Components Selection
