The magic land adventure
Hey adventurous travelers! We've been invited to the grand castle to celebrate the birth of the new princess! It's a tremendous honor! We can't miss this party, or we'll lose our honor as adventurers and heroes of the lands!!
Let's begin this long journey to the castle! Many quests and challenges await us until we arrive and enjoy such an honorable celebration. I've heard that the kings offer a grand banquet and give very valuable pieces as a present to those who attend!

CHAPTER 1
the Drawbridge
On top of a hill stands the Crystal Castle, but the drawbridge is broken... and no one can get inside... We need to enter this castle so we can get weapons, armor and food to survive on our journey. They told us that if we help them build the bridge, they'll give us everything we need for free!
YOUR MISSION
👉 Mission: Build an automatic bridge with a motor. The bridge must go up and down. 💡 Sensors/actuators: motor
Do you need help with instructions?
CODE IT
Open Makecode Microbitand create a new project. You will have to download one extension We are ready to code it!
CODE IT
To prevent it from breaking, we are going to tell the program to do that movement for a limited time.
We will use the buttons on our micro:bit A and B as input.
Now let's set the motors.

CONGRATULATIONS
The castle's inhabitants are very grateful. They've offered you weapons, armor, and food to begin your adventure. The kingdom has also recognized you for your kindness.

CHAPTER 2
the DRAGON
With the resources obtained in the castle we can continue our way to the king's castle. But beware! On the way, we encountered a dragon!
We don't know if it's good or bad!
YOUR MISSION
👉 Mission: Create a dragon that flaps its wings when it senses someone nearby. 💡 Sensors/actuators: motor + ultrasonic sensor
Do you need help with instructions?
CODE IT
Open Makecode Microbitand create a new project. You will have to download two extensions We are ready to code it!

Now you just need to make it stop when it doesn't detect anything in front of it
We will use the ultrasonic sensor to start moving the motor
Now let's set the motors.

YOUR MISSION
👉 Mission: Create a light and sound show when the enviroment is dark 💡 Sensors/actuators: colored LEDs. Optional: motors to move decorations. Micro:bit for the light sensor
Download the code!
We have 3 different situations:
The sensor detects the black line in both side of the sensor
The sensor detects the black line on the right side of the sensor
The sensor detects the black line on the left side of the sensor
That means we need to add a conditional IF - ELSE
Because it will move its wings IF the ULTRASONIC SENSOR detects something in a distance less than...
We want the wings to flap up and down... That's why we need to add a Pause to determine how long the motor will be moving. Set one direction (20%) and the other one (-20%) Add the pause to both of them.
When both sides of the sensor detect the line, the cart is going to move forward.
When the left side of the sensor detects the line, the cart is going to turn right.
When the right side of the sensor detects the line, the cart is going to turn left.
