dfrobot i2c lcd module free sample

This is another great I2C 16x2 LCD display compatible with Gadgeteer modules from DFRobot. With limited pin resources, your project will quicly run out of resources using normal LCDs. With this I2C interface LCD module, you only need 2 lines (I2C)to display the information.If you already have I2C devices in your project, this LCD module actually cost no more resources at all. The adress can be set from 0x20-0x27. Fantastic for Arduino or gadgeteer based projects.

Now the offer is much bigger, and they came in all sizes. DFRobot send me the SPI/I2C Monochrome 60x32 0.5" OLED Display for Arduino for my next project.

Software frameworks for developing menu-based interfaces in C or C++ for microcontrollers often have a steep learning curve and can be difficult to make rapid design changes in, as often everything interacts with everything else. The goal of this project was to use the XOD graphical programming environment to provide the ability to rapidly prototype menu-driven interfaces for Arduino-compatible microcontroller projects using a drag-and-drop/WYSIWYG style of interface. The output and input parameters of the generated menu structure are modular and generic and should be able to be used with a wide variety of input sources (switches, buttons, encoders) and produces a sequence of plain text outputs which can be fed to a wide variety of XOD-supported display types, including multi-line text LCD modules as used in this example.

At the right of the patch editing screen in XOD are four nodes connected up in a descending fashion. From top to bottom there"s first an analog input-type node, which is selected to be connected to one the Arduino"s analog input ports. In my tests I"ve been using an Arduino Uno with an ATMega328 8 bit processor, with a 16x2 LCD/keypad shield connected on top of it. The keypad on the shield is connected via the shield pins to the Arduino"s "A0" analog input, and the hardware generates voltages of differing levels to signal to the Arduino which buttons on the pad are depressed.

Other than the "reset" button on the keypad which doesn"t interface to the Arduino sketch directly, this type of display shield provides four directional buttons - up, down, left, and right, a "select" button. The second node down fed by the analog input node contains code which reads the differing voltage levels and outputs pulse-type triggers depending on which button is pressed. A "timeout" input is provided so an XOD developer can adjust the debounce timeout of the LCD shield keypad to avoid false triggering, adjusted to a particular application"s button or switch type.

Following that node is a stock 16x2 LCD controller module from the XOD environment standard library, but any type of display that a module is available for can be used to display the output text here.

In this session we will create a device that can measure the temperature and humidity in the environment and display the results in real time on a LCD screen.

Put libraries “dht11” and “LiquidCrystal_I2C” into Arduino IDE’s libraries folder. If you don’t know how to load libraries, please refer to Experiment 12 for details.

Once you are familiar with Arduino, you can even add network module to your controller to allow you to post the real-time data collected to an online platform like weibo or twitter.
