Hello,

I have a problem in which my lcd display does not blink the cursor according to potientiometer movement. I have made a menu. Code Attatched here :-

// include the library code:
#include <LiquidCrystal.h>

// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(7, 8, 9, 10, 11, 12);

int potPin1 = A1;
int potPin2 = A2;

void setup()
{
  // set up the LCD's number of columns and rows:
  lcd.begin(16, 2);
  analogWrite(3, 10);
}

void loop() {
  lcdf();
  int j1 = map(potPin1, 0, 1023, 1, 5);
  if (j1 = 2) {
    lcd.setCursor(5, 0);
    lcd.blink();
  }
  if (j1 = 3) {
    lcd.setCursor(13, 0);
    lcd.blink();
  }
  if (j1 = 4) {
    lcd.setCursor(5, 1);
    lcd.blink();
  }
  if (j1 = 5) {
    lcd.setCursor(13, 1);
    lcd.blink();
  }
}

void lcdf() {
  lcd.setCursor(0, 0);
  lcd.print("Vol+    Vol-");
  lcd.setCursor(0, 1);
  lcd.print("LED+    LED-");
}

pls check it and see if i have missed anything

very thanks,
Abeer

Oops (times four)

3

meaning?

4

it shows the places where the blink should be but it is on all 4 places. sorry if it's a dumb mistake as i am only a child

5

Meaning that you do not use a single equals sign to carry out a comparison

6

ohhh......i forgot as i dont do much coding nowadays

7

have another prob

8

it is not blinking....here is my updated code

// include the library code:
#include <LiquidCrystal.h>

// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(7, 8, 9, 10, 11, 12);

int potPin1 = A1;
int potPin2 = A2;

void setup()
{
  // set up the LCD's number of columns and rows:
  lcd.begin(16, 2);
  analogWrite(3, 10);
  lcdf();
}

void loop() {
  int j1 = map(potPin1, 0, 1023, 1, 5);
  if (j1 == 2) {
    lcd.setCursor(5, 0);
    lcd.blink();
  }
  if (j1 == 3) {
    lcd.setCursor(13, 0);
    lcd.blink();
  }
  if (j1 == 4) {
    lcd.setCursor(5, 1);
    lcd.blink();
  }
  if (j1 == 5) {
    lcd.setCursor(13, 1);
    lcd.blink();
  }
}

void lcdf() {
  lcd.setCursor(0, 0);
  lcd.print("Vol+    Vol-");
  lcd.setCursor(0, 1);
  lcd.print("LED+    LED-");
}

pls help

What do you think that lcd.blink() does ?

12

it blinks the cursor i think?

13

Have you read

"Display the blinking LCD cursor. If used in combination with the cursor() function, the result will depend on the particular display."

in LiquidCrystal - Arduino Reference

Exactly which display do you have ?

14

You have a setCursor(), but not "cursor()"

Read this very carefully

"Display the blinking LCD cursor. If used in combination with the cursor() function, the result will depend on the particular display."

Does your code use the cursor() function ?

19

So go study, and leave the hobby electronics for later.

Learn to prioritise.

um.....no.....

21

ok....i meant that my listening test is coming up

Did you read the quoted text carefully as I suggested ?
