Before wiring the LCD screen to your Arduino or Genuino board we suggest to solder a pin header strip to the 14 (or 16) pin count connector of the LCD screen, as you can see in the image above. In Arduino based embedded system design, the Liquid Crystal Display modules play a very important role. We are only using the LCD to write on, nothing more. Interface an LCD with an Arduino. DIY Arduino Uno LCD Voltmeter. GitHub Gist: instantly share code, notes, and snippets. LCD modules are most frequently used devices specially in Arduino based electronic projects. We will begin our experiments by hooking up the LCD1602 to an Arduino Uno and running a few of the example sketches included with the Arduino IDE. PIN12 or D5 to PIN4 of ARDUINO UNO. Plug and play with any Arduino 'classic' - UNO, duemilanove, diecimilla, etc. In the start of the program (setup() section) the user will get a opening screen such as this: "Press A to start" "the program init". Codes below are used for set the pin as input or output, and set 16x2 LCD display.
