Val=analogRead(1) // read the analog in value:ĭata = (double) val * (5/10. Int val // variable to store the value coming from the analog pinĭouble data // variable to store the temperature value coming from the conversion formula Lcd.setCursor(0, 0) // set the LCD cursor position LiquidCrystal lcd(8, 9, 4, 5, 6, 7) // select the pins used on the LCD panel This program takes the temperture sensor LM35 for example. Reads an analog input on pin 1, prints the result to the LCD. Plug the LCD Keypad to the UNO(or other controllers) Set the location at which subsequent text written to the LCD will be displayed. begin() needs to be called before any other LCD library commands.for example: The NANO has two more analog pins, however. The Arduino NANO pins, similar to the UNO, is divided into digital pins, analog pins and power pins. This Arduino NANO Pinout diagram reference is a handy guide for using this board: Arduino NANO Pinout Description. Initializes the interface to the LCD screen, and specifies the dimensions (width and height) of the display. The Arduino NANO is a smaller, breadboard-friendlier version of the Arduino UNO. The RW pin can be tied to ground instead of connected to a pin on the Arduino if so, omit it from this function's parameters. If the former, omit the pin numbers for d0 to d3 and leave those lines unconnected. The display can be controlled using 4 or 8 data lines. LiquidCrystal(rs, enable, d4, d5, d6, d7)Ĭreates a variable of type LiquidCrystal. Expanded Analog Pinout with standard DFRobot configuration for fast sensor extension.Integrate a potentiometer for adjusting the backlight.RST button for resetting arduino program.5 Push buttons to supply a custom menu control panel.The key value is read through a 5 stage voltage divider. To save the digital IO pins, the keypad interface uses only one ADC channel. Despite its compact design, the Nano V3 corresponds almost completely to the.

The keypad consists of 5 keys - select, up, right, down and left. The microcontroller has an original chip and is therefore fully Arduino compatible. It consists of a 1602 white character blue backlight LCD. The LCD Keypad shield is developed for Arduino compatible boards, to provide a user-friendly interface that allows users to go through the menu, make selections etc. It also expands analog pins for easy analog sensor reading and display. The LCD shield supports contrast adjustment and backlit on/off functions. Analog Pin 0 is used to read the push buttons. Pins 4, 5, 6, 7, 8, 9 and 10 are used to interface with the LCD. The Seeeduino Nano is a compact board that is fully compatible with the Arduino Nano on pinout on sizes. It includes a 2x16 LCD display and 6 momentary push buttons. This is a very popular LCD Keypad shield for Arduino or Freeduino board. LCD_KeyPad_Shield_For_Arduino_SKU_DFR0009-DFRobot
