Introduction

LCD2004, or 2004 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 5x8 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 2004 means it displays 4 rows of 20

characters.

Generally, LCD2004 has parallel ports, that is, it would control several pins at the same time. LCD2004 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.

2/14/2018 LCD2004 Module - Wiki 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 LCD2004_for_Raspberry_Pi to the Raspberry Pi wget http://wiki.sunfounder.cc/images/b/bb/LCD2004_for_Raspberry_Pi.zip Step 3: Extract the package unzip LCD2004_for_Raspberry_Pi.
