I've already used a soil moisture sensor so my first assignment was to integrate a temperature/humidity sensor into the greenhouse. Future iterations will hopefully allow us to tackle these engineering issues which will make the greenhouse more sustainable. So for now we haven't spent time calculating economic value or carbon footprint. The main objective of Så Ett Frö is education amongst grades 7-9. My job was to automate a small greenhouse using my budding Arduino skills. Så Ett Frö ( Plant a Seed) is a collaboration with HSB Living Lab, a 10-year-long experiment which uses technology to help build more sustainable housing building. Lcd.My friend Afra invited me to participate in a conference in Sweden involving sustainable urban greenhouse solutions. begin(9600) // Used to type in characters *-( Declare Constants )-*/ /*-( Declare objects )-*/ // set the LCD address to 0x27 for a 20 chars 4 line display // Set the pins on the I2C chip used for LCD connections: // addr, en,rw,rs,d4,d5,d6,d7,bl,blpol LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE) // Set the LCD I2C address /*-( Declare Variables )-*/ //NONE void setup() /*-( SETUP: RUNS ONCE )-*/ #include // Comes with Arduino IDE // Get the LCD I2C Library here: // // Move any other LCD libraries to another folder or delete them // See Library "Docs" folder for possible commands etc.

They willĭisplay characters you type on the Serial Monitor screen on the LCD. There are many advanced functions.īelow are Example Software Sketches for different displays. See the "Docs" folder within the Library folder. LiquidCrystal_I2C Library Support Functions See a LCD used in the Temperature-Humidity project. Start clockwise and backĭown to where the characters are bright and the background does not have If you don't see any characters, adjust it. NOTE: The Blue Potentiometer (Photo) adjusts Contrast. SCL (clock line) is on analog input pin 5. On most Arduino boards, SDA (data line) is on analog input pin 4, and It is easiest with a 4-wire cable (supplied) that plugs into the Sensor Shield communications connector.īut you can wire it directly yourself if needed: There are 4 pins on the display. This unit connects with 4 wires including Vcc and Gnd. More information about I2C/TWI (Wikipedia)
Your project, this LCD module actually uses no more pins at all. With this I2C interface LCD module, you only need 2 You are doing more than a simple project, you may be out of pins using a Would need 6 pins: RS, EN, D7, D6, D5, and D4 to talk to the LCD. To use this type LCD directly with Arduino, you On Yellow) background: it is difficult to get a good digital photo due
