• 12 rows of 10 pixels each

• Large characters are 2 rows and 2 columns

Displaying Text in Grid Mode
Step 1:
Pick Display Block
Step 2:
Click on “Switch Modes” icon and hover over “text”. Then click on “grid”. The icon will change into a square with dots.
Step 3:
Use the box on the top right to enter the text you want to display

Challenge 1
• Can you write a program to display text in the middle of the screen? Display “Hello World”
• Make the display block run for 3 seconds
• Can you also move while doing this?

Challenge 2: Two lines of Text
• Now what if you want “Hello” to appear on one line and “World” to appear on the next line?

Hint: You will use two display blocks and don’t clear the screen on the second display block otherwise the first word will disappear!
