About Micro bit

From dancing robots to banana keyboards, your micro: bit has all the features

you need to code awesome stuff - the possibilities are endless!

In 2015, BBC launched the second programmable micro computer, and it is a

super mini computer which can be put in your pocket, meanwhile, it can help

young people learn basic programming knowledge with low cost. In 2016, 100

million micro computers have been provided for middle and primary school

students in Britain.

www.adeept.com

Your micro: bit has the following physical features:

Buttons

Pins �

Light Sensor

LED stands for Light Emitting Diode. The micro: bit has 25 individually-programmable LEDs, allowing you to display text, numbers, and images.

There are two buttons on the front of the micro: bit (labelled A and B). You can detect when these buttons are pressed, allowing you to trigger code on the device.

There are 25 external connectors on the edge connector of the micro: bit, which we refer to as 'pins'. Program motors, LEDs, or other electrical components with the pins, or connect extra sensors to control your code! The five big pins connect with the annular hole, and marked as 0, 1, 2, 3V, GND, representing P0, P1, P2, 3V power output

www.adeept.com

Temperature Sensor

Accelerometer

By reversing the LEDs of the screen to become an input, the LED screen works as a basic light sensor, allowing you to detect ambient light.

This sensor allows the micro: bit to detect the current ambient temperature, in degrees Celsius.

An accelerometer measures the acceleration of your micro: bit; this component senses when the micro: bit is moved. It can also detect other actions, e.g. shake, tilt, and free-fall.

www.adeept.com

Compass

Bluetooth

The compass detects the earth's magnetic field, allowing you to detect which direction the micro: bit is facing. The compass has to be calibrated before it can be used.

'Calibrating' the compass ensures the compass results are accurate. For the JavaScript Blocks Editor, use the 'calibrate compass' block. To calibrate the compass in Python use compass.calibrate().

The radio feature allows you to communicate wirelessly between micro: bits. Use the radio to send messages to other micro: bits, build multiplayer games, and much more!

A BLE (Bluetooth Low Energy) antenna allows the micro: bit to send and receive Bluetooth signals. This allows the micro: bit to wirelessly communicate with PCs, Phones, and Tablets, so you can control your phone from your micro: bit and send code wirelessly to your device from your phone!

www.adeept.com

USB Interface

The USB interface allows you to connect the micro: bit to your computer via a micro-USB cable, which will power the device and allow you to download programs onto the micro: bit.

#define button value

keys=[["1","2","3","A"],

["4","5","6","B"],

["7","8","9","C"],

["*","0","#","D"]]

While True:

row = 0

colume = 0

pin12.read_digital()

#Check row button

row = pin12.read_digital()+

pin13.read_digital()*2+pin14.read_digital()*3+pin15.read_digital()*4

pin0.read_digital()

pin1.read_digital()

pin2.read_digital()

pin8.read_digital()

#Check colume button

colume = pin0.read_digital()+

pin1.read_digital()*2+pin2.read_digital()*3+pin8.read_digital()*4

if (colume+row != 0):

display.scroll(str(keys[colume-1][row-1]))

sleep(100)

5. Click “flash” and download the code onto the micro: bit 6. Now, we just need to press any key, the matrix lamp will display in a rolling way. (Notice: pressing multi-keys at the same time is not supported, otherwise, there will be messy code)
