MISSION 3
Light Sensor to Detect When Vampire Zombies Are Awake
Vampire zombies only come out when it’s dark. Let’s create a light sensor that tells us when it’s dark so that we know when to be on alert.
Algorithm
For the micro:bit, the alarm will be some text across the LEDs. For the Circuit Playground Express, we’ll flash the lights.
SELECTION
In coding, we call the if statement in the above algorithm Selection. If statements are a big part of coding. We use them to check on things. I like to use the example:
In an if statement, you’re checking ...
