Question

Constant Current Code for Arduino

Develop a Constant Current Program in C and upload it into your Arduino

#include <LiquidCrystal.h>

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

Answer 1

For connecting the LCD to arduino following are the instructions:

1. Connect PIN1 or VSS to ground, PIN2, VCC to +5v power, PIN3/VEE to ground, PIN4/Register Selection to PIN0 of ARDUINO UNO, PIN5/RW to ground, PIN6/Enable) to PIN1 of ARDUINO UNO, PIN11/D4 to PIN8 of ARDUINO UNO, PIN12/D5 to PIN9 of ARDUINO UNO, PIN13/D6 to PIN10 of ARDUINO UNO, PIN14/D7 to PIN11 of ARDUINO UNO

After connnecting all the points we have write the C programme and burn it on the IC using burner for auduino.

The LCD interfacing will be 16X2 and the programme to print "my name is ABC" on LCD will be

#include <LiquidCrystal.h>

lcd.begin(16, 2);

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

lcd.print("my name is abc");

C code porgramme:

#include <LiquidCrystal.h>

// initialize the programme with the numbers of pins

LiquidCrystal lcd(12, 11, 5, 4, 3, 2); /// select register pin, enabe D4 pin, d7 pin and d6 pin

void setup()

{

// Set up LCD's number of columns and rows:

lcd.begin(16, 2);

}

void loop()

{

// set cursor to column 0, line 1

lcd.print(" my name is abc");//print name

lcd.setCursor(0, 1); // set cursor to column 0, line 2

lcd.print("what do you do");//print name

delay(800);//delay of 0.8sec

lcd.scrolldisplayLeft(); //shifting data on LCD

lcd.setcursor(0, 0); // set the cursor to column 0, line1

}

The following would be the ouput

my name is abc

what do you do
