• Arduino Uno board
• Parallax 16x2 Serial LCD
  
  

1. Insert the 3 pins on the rear of the LCD module into the breadboard
2. When mounted like the photo, the top pin is the data, center is +5v, and bottom pin is ground. Data connects to pin 2, +5v connects to +5 and Ground connects to GND.
   * optional: use a 3-socket connector with wires to connect the LCD directly to the Arduino module
3. Connect three patch wires between the LCD module to the Arduino pins identified in the schematic
4. Connect the Arduino unit to your computer with the USB cable
5. Open the appropriate Hello World sketch into the Arduino software and upload it to your module to test the LCD display.
