Bring your first character to life. Learn to use 'events' so your robot reacts instantly with a laugh and an animation when you 'tickle' it with a clap.
-
BasicThe Spirit Level: Is It Straight?
Use your phone's tilt sensor and advanced conditionals ('Else If') to build a tool that tells you if something is perfectly level.
-
BasicBuild a Fall Detector
Learn how to measure total acceleration with your phone's motion sensor to create a system that can detect a sudden fall.

Teach your program to 'think'. Learn how to use 'If...' conditionals so your prototype can make decisions and set off an alarm to guard your secret cookie box.
-
IntermediateThe Sunflower Alarm Clock
Learn to handle two paths with 'If... Else...' logic. Build a smart alarm clock that switches on with the light, like a sunflower waking up with the sun.
-
IntermediateFlight of the Night Bat
Strengthen your command of 'If... Else...' logic by flipping the condition around. Create a virtual bat that only wakes up and takes flight when the room goes dark.
