💡 Hint

Common Mistakes

Using 1 instead of 0 for the first column.

Confusing row and column order.

The first column on the LCD is column 0, so we use 0 as the first argument in setCursor.

2fill in blank

medium

Complete the code to move the cursor to the third column on the second row.

Arduino

lcd.setCursor([1], 1);

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 3 instead of 2 for the third column.

Mixing up row and column numbers.

Columns are zero-indexed, so the first column is 0, the second is 1, and the third column is 2.

hard

Fix the error in the code to correctly position the cursor at column 4, row 0.

Arduino

lcd.setCursor(4, [1]);

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 1 instead of 0 for the first row.

Confusing row and column arguments.

The first row is row 0, so the second argument to setCursor should be 0.

4fill in blank

hard

Fill both blanks to set the cursor to the last column on the last row of a 16x2 LCD.

Arduino

lcd.setCursor([1], [2]);

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 16 for the last column (out of range).

Using 2 for the last row (out of range).

For a 16x2 LCD, columns go from 0 to 15, so last column is 15. Rows go from 0 to 1, so last row is 1.

5fill in blank

hard

Fill all three blanks to set the cursor to column 0, row 1, and then print 'Hello'.

Arduino

lcd.setCursor([1], [2]);
lcd.print([3]);

Drag options to blanks, or click blank then click option'

B1

C"Hello"

D"World"

💡 Hint

Common Mistakes

Using 1 for the column instead of 0.

Using 0 for the row instead of 1.

Forgetting quotes around the string.

Column 0 and row 1 set the cursor to the first column of the second row. Then printing "Hello" displays the text there.
