LCD interfacing with Arduino Nano
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
Select the best posible component which match the following requirements
- Arduino board: Arduino uno or Arduino nano with Atmega328P
- 16*2 LCD Displya
- Connecting Wire
- PCB board
Step 2 : Make The PCB on genral Perpose board as shown in Circuit Diagram.
