Description:
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.
It also is known as Arduino LCD1602 character LCD expansion board with PCB Immersion Gold processing technology, high-quality materials with 2 lines 16 character LCD, not only has the contrast knob, backlight selector switch, also has four directional buttons, an option button, and a reset button. This 1602 LCD expansion board simplifies the circuit in the true sense, this board can directly connect Arduino Duemilanove to the controller.
Note: After you run the code, characters may not appear on the LCD. You need to adjust the contrast of the screen (the gradual change from black to white) by spinning the potentiometer clockwise or counterclockwise until the screen displays characters clearly.
