Ver 1.0

Bluguard Maqueen is a micro:bit plug-and-play module allows children to learn graphic

programming in a most entertaining and fun way. It is nurturing children's logical thinking

and programming skills.

Bluguard Maqueen is accessible to both Mind+ and Makecode programming platform

now. Mind+ is a graphical programming platform supporting python, Arduino and other

platforms. On the other hand, MakeCode programming platform allowing users to execute

functions by dragging and snapping the graphical blocks.

Suggest Age: 8 +

Adult supervision is recommended for children under 8 years old.

In this chapter, users will learn how to use ultrasonic to read the distance of ultrasound.

The ultrasonic detects the obstruction in front and the distance will be displayed on the dot-

matrix screen in centimeters.

Step of Makecode Graphical Program:

1. Add the block ‘forever’(Basic) & ‘show number [0]’(Basic). Drag the block ‘show

number [0]’(Basic) into block ‘forever’(Basic).

2. Add the block ‘read ultrasonic sensor cm’(Maqueen) and replace it at ‘[0]’.

3. Go to ‘connect device’after connecting micro:bit with cable. Just follow instructions and

this step is just one-time setup.

4. Click Download to transfer your code to micro:bit.

5. Move your hand towards the ultrasonic and the micro:bit will show you the distance in

cm.

The car does not move in the darker light, and as the flashlight illuminates the LED, the

vehicle's forward speed begins to increase as the intensity of the light increases.

Step of Makecode Graphical Program:

1. Add the block ‘forever’(Basic), ‘if…then...else’(Logic) and ‘[0] < [0]’(Logic).

2. For condition ‘if’, replace left ‘[0]’ with ‘[light level]’(Input). Change the symbol ‘[<]’to

‘[>]’and value another ‘[0]’ to ‘[80]’.

3. For condition ‘then’, add the block ‘motor [left] move [Forward] at speed [0]’(Maqueen)

and replace ‘[0]’ with ‘[light level]’(Input). Duplicate ‘motor [left] move [Forward] at

speed [light level]’(Right-click->Duplicate) and change ‘[left]’to ‘[right]’.
