LCD1602, or 1602 character-type liquid crystal display, is a kind of dot matrix module to show letters, numbers, and characters and so on. It's composed of 5x7 or 5x11 dot matrix positions; each position can display one character. There's a dot pitch between two characters and a space between lines, thus separating characters and lines. The number 1602 means on the display, 2 rows can be showed and 16 characters in each.<br>

Introduction

Lcd1602-1.jpg

LCD1602, or 1602 character-type liquid crystal display, is a kind of dot matrix module to show letters, numbers, and characters and so on. It's composed of 5x7 or 5x11 dot matrix positions; each position can display one character. There's a dot pitch between two characters and a space between lines, thus separating characters and lines. The model 1602 means it displays 2 lines of 16 characters.
Generally, LCD1602 has parallel ports, that is, it would control several pins at the same time. LCD1602 can be categorized into eight-port and four-port connections. If the eight-port connection is used, then all the digital ports of the SunFounder Uno board are almost completely occupied. If you want to connect more sensors, there will be no ports available. Therefore, the four-port connection is used here for better application.

Components
- 1 * SunFounder Uno Board
- 1 * Breadboard
- 1 * LCD1602
- 1 * Potentiometer (50kΩ)
- 1 * USB Cable
- Several Jumper Wires


Experimental Procedures
Note: Before connecting circuit, need to plug the pin headers onto a breadboard, and then put the LCD1602 on to it for easy soldering.

Step 3: Select correct Board and Port
Step 4: Upload the sketch to the SunFounder Uno board


Experimental Phenomenon
Note: You may need to adjust the potentiometer on the LCD1602 until it can display clearly.
You should now see the characters "SunFounder" and "hello, world! " rolling on the LCD.

The Experiment for Raspberry Pi

Components
- 1 * Raspberry Pi
- 1 * Breadboard
- 1 * LCD1602
- 1 * Potentiometer
- Several Jumper Wires


Experimental Procedures
Step 1: Build the circuit (please be sure the pins are connected correctly. Otherwise, characters will not be displayed properly):

LCD1602/2004 SunFounder Uno board
K GND
A 3.3V
D7 GPIO18
D6 GPIO23
D5 GPIO24
D4 GPIO25
D0-D3 No Connected
E GPIO22
R/W GND
RS GPIO27
OV Connect to the middle pin of potentiometer
VDD 5V
VSS GND

Note: After you run the code, characters may not appear on the LCD1602. You need to adjust the contrast of the screen (the gradual change from black to white) by spinning the potentiometer clockwise or anticlockwise, until the screen displays characters clearly.

Step 2: Transfer the package LCD1602_for_Raspberry_Pi to the Raspberry Pi

wget http://wiki.sunfounder.cc/images/8/87/LCD1602_for_Raspberry_Pi.zip

Step 3: Extract the package

unzip LCD1602_for_Raspberry_Pi.zip

(For C Language Users)
Step 4: Get into the folder of code

cd LCD1602_for_Raspberry_Pi/C

Step 5: Compile

gcc lcd1602.c –o lcd1602 –lwiringPiDev –lwiringPi

Step 6: Run

sudo ./lcd1602

(For Python Users)
Step 4: Get into the folder of code

cd LCD1602_for_Raspberry_Pi/Python

Step 5: Run

sudo python lcd1602.py


Experimental Phenomenon
You should see two lines of characters displayed on the LCD1602: “hello, world! ” , “SunFounder”.
