Arduino Workshop - Parallel LCD Project 1: DFRobot Parallel LCD

Hardware Required: Arduino Uno board DFRobot 16x2 LCD Shield

Schematic: No schematic necessary. All connections are made by installing the LCD Shield directly onto the Arduino's sockets. Note: The boards tested use different signal and data pins than the default examples in the LCD Library. Our LCD Shield uses pin 8 for Register Select, Pin 9 for Enable, and pins 4, 5, 6, 7 for data - connecting to Arduino pins 12, 11, 5, 4 , 3 and 2, respectively. You cannot change these pin connections, but must make sure your Sketch code specifies the actual pins being used: // the syntax to specify the connections used by the LCD Shield should read: LiquidCrystal lcd(8, 9, 4, 5, 6, 7);

Project Steps: Insert the LCD Shield module directly into the matching sockets on the Arduino. Open the appropriate Hello World sketch into the Arduino software and upload it to your module to test the LCD display. Things to try: (Arduino Sketch examples) HelloWorld - Basic communication test AutoScroll - demonstrates display's automatic scrolling feature Blink - Change block cursor style: blinking or non-blinking Cursor - Hide or show the underline cursor CustomCharacter - Demonstrates loading and displaying custom characters on a display Display - demonstrates turning the display text on & off (hide, unhide) RandomMessage - Randomly change a text message on the display Scroll - shift the message display text left or right SetCursor - Demonstrates direct positioning of the cursor before printing TextDirection - Demonstrates right-to-left and left-to-right printing using the LCD library
