2. Objective of the lesson
Use Block Editor to make Fading Heart
All of you will:
Create a Heart that fades up
Most of you will:
Change the speed of the fade
Some of you will:
Display a message once the Heart has reached maximum brightness

3. Fading Heart 2
This heart will fade on very gradually
We will create a variable. A variable will change. This will be our brightness
Create a variable, set item
Change the Item, which is the name of the variable, to be Brightness
Set this to equal 0
Add a forever loop. Set the brightness to equal the variable brightness.
At the moment this is 0 so you will see no heart

4. We will add a short pause
Then increase the brightness slightly
This loops and the brightness increases slightly each time

5. Challenge
1. Experiment with the ‘pause’ and the ‘change brightness’ to change the fade effect
2. Replace forever with a ‘while do’ loop to check that Brightness is < 255. If it is, then
the image fades up
3. Once Brightness has reached 255 make it show string “Love”
