#ARDUINO NANO PINOUT LCD DOWNLOAD#

To simplify communication between Arduino IDE and LCD module, we need to download LiquidCrystal library to make use of a built program in Arduino.

PIN6 or E (Enable) to PIN 11 of ARDUINO UNO.

PIN4 or RS (Register Selection) to PIN 12 of ARDUINO UNO.

PIN3 or V0 to potentiometer and other leads of potentiometer connected to arduino.

PIN1 or VSS and PIN5 or RW (Read/Write) are commonly to ground.

The connections which are done for LCD are given below:

So, it will have 16×2 32 characters in total and each character will be made of 5×8 Pixel. There are a lot of combinations available like 8×1, 8×2, 10×2, 16×1, etc. Pin 16 (CATHODE/LEDK/-ve pin of the LED): This pin is connected to GND. 16×2 LCD is named so because it has 16 Columns and 2 Rows. MCP2515 Library for using CAN Communication and LiquidCrsytal Library for using 16x2 LCD with Arduino. Pin15 (ANODE/LEDA/+ve pin of the LED): This pin is connected to +5V (DHT11) sensor data from Arduino Nano to Arduino Uno via CAN bus module MCP2515. For example, MISO on Nano’s ICSP header is connected to MISO / digital pin 12. In 4-wire mode, only four pins are connected to the microcontroller unit like 0 to 3, whereas in 8-wire mode, 8-pins are connected to microcontroller unit like 0 to 7. The Arduino Nano, as the name suggests is a compact, complete and bread-board friendly microcontroller board. These pins are connected in two-wire modes like 4-wire mode and 8-wire mode. Pins 7-14 (Data Pins/D0……D7): These pins are used to send data to the display. Pin 6 (Enable(E)): This pin should be held high to execute Read/Write process, and it is connected to the microcontroller unit & constantly held high. Pin5 (Read/Write(RW)): This pin toggles the display among the read or writes operation, and it is connected to a microcontroller unit pin to get either 0 or 1 (0 = Write Operation, and 1 = Read Operation). Pin4 (RS/Register Select/Control Pin): This pin toggles among command or data register, used to connect a microcontroller unit pin and obtains either 0 or 1(0 = data mode, and 1 = command mode). Pin3 (V0/VEE/Control Pin): This pin regulates the difference of the display, used to connect a changeable POT that can supply 0 to 5V. Pin2 (VCC/VDD/Source Pin): This is the voltage supply pin of the display, used to connect the supply pin of the power source. Pin1 (VSS/Ground): This is a GND pin of display, used to connect the GND terminal of the microcontroller unit or power source. Now in the 14 pins there are 8 data pins (7-14 or D0-D7), 2 power supply pins (1&2 or VSS&VDD or GND&+5v), 3rd pin for contrast control (VEE-controls how thick the characters should be shown), and 3 control pins (RS&RW&E). One can power or leave the back light pins. In 16×2 LCD there are 16 pins over all if there is a back light, if there is no back light there will be 14 pins. Working with both 8-bit and 4-bit mode.

Each character is built by a 5×8-pixel dots.Consists of two rows and each row print 16 characters.Alphanumeric LCD display (alphabets, number, special characters).
