Case 02: Speed Up Gradually
Purpose
In case 01, we can find the Cutebot moves too fast to go steadily(the universal wheel goes off the ground) at the beginning.
We will learn to gradually speed up the car for a steady move at the beginning in this case.
Materials

Software Platform
Programming
Step 1
Click the "Advanced" to see more choices in the MakeCode drawer.
A codebase is required for Cutebot programming, click “Add Package” at the bottom of the drawer, search Cutebot in the dialogue box and download it.
Note: If you met a tip indicating incompatibility of the codebase, you can continue with the tips or build a new project there.
Step 2
Choose "show icon" in the On startbrick.
Set the speed variable to 0 which means the on start speed is 0.
Step 3
Drag setting speed bricks for left and right wheel and set the value as speed in "forever" brick, then add one to speed.
If speed is 100 which is the maximum speed, set speed to 0 and restart it.
