<br>[[File:Ks0306-6.png|500px|frameless|thumb]]<br>

==micro:bit Using Method==

===Step 1: Connect It===
Connect the micro:bit to your computer via a micro USB cable. Your micro:bit will show up on your computer as a drive called 'MICROBIT'. 
<br>[[File:Ks0305-6.png|800px|frameless|thumb]]<br>


===Step 2: Program It===
Using micro bit MakeCode Block editor https://makecode.microbit.org/, write your first micro:bit code. You can drag and drop some example blocks and try your program on the Simulator in the Javascript Blocks Editor, like in the image below. 
<br>[[File:Ks0305-1.png|600px|frameless|thumb]]<br>

Click the JavaScript, you can see the corresponding program code. Shown as below figure.
<br>[[File:Ks0305-2.png|700px|frameless|thumb]]<br>

===Step 3: Download It===
Click the Download button in the editor. This will download a 'hex' file, which is a compact format of your program that your micro:bit can read. 
Here you can name the project as LED1, then click “Save”. Shown below.
<br>[[File:Ks0305-3.png|600px|frameless|thumb]]<br>

Once the hex file has downloaded, copy it to your micro:bit just like copying a file to a USB drive. On Windows find the microbit-LED1 file, you can right click and choose "Send To→MICROBIT."
<br>[[File:Ks0305-4.png|600px|frameless|thumb]]<br>  
<br>[[File:Ks0305-5.png|600px|frameless|thumb]]<br>


===Step 4: Play It===
The micro:bit will pause and the yellow 5*5 LED on the back of the micro:bit will display the images while your code is programmed. 
<br>[[File:Ks0305-6.png|800px|frameless|thumb]]<br>

You can power it using USB cable or battery. The battery holder need to connect two 1.5V AA batteries. Shown below.

'''Testing Result''' <br>
Done downloading the code into micro:bit, you can see that the brighter the photocell senses, the darker the LED; the darker the photocell senses, the brighter the LED.

=== Lesson 10: Active Buzzer ===

'''Description'''<br>
There are two kinds of buzzer, active buzzer and passive buzzer. In this lesson, we will use micro:bit to drive an active buzzer. The active buzzer inside has a simple oscillator circuit which can convert constant direct current into a certain frequency pulse signal. Once active buzzer receives a high level, it will produce an audible beep. 

'''Hardware Required''' <br>
* micro: bit main board *1<br>
* keyestudio T-type adapter *1<br>
* USB cable *1<br>
* Active buzzer *1<br>
* Breadboard *1<br>

'''Testing Result'''<br> 
Finally, you can hear the active buzzer beep for 0.5 seconds, then stop and beep for 0.5 seconds circularly.

=== Lesson 11: Passive Buzzer ===

'''Description'''<br>
You have learned about the active buzzer. So this lesson will use a passive buzzer to play a song. It comes with a fun application, give it a try! Since the passive buzzer has no oscillator inside, DC signal can’t make it beep, so need to use square-wave to drive it.

'''Hardware Required''' <br>
* micro: bit main board *1<br>
* keyestudio T-type adapter *1<br>
* USB cable *1<br>
* Passive buzzer *1<br>

=== Lesson 12: Driving Servo Motor ===

'''Description''' <br>
Servo motor is a position control rotary actuator. It mainly consists of housing, circuit board, core-less motor, gear and position sensor. Servomotor comes with many specifications. But all of them have three connection wires, distinguished by brown, red and orange (different brand may have different color).

When one end of tilt switch is lower than the horizontal position, it performs a turn-on operation; while another end is lower than the horizontal position, tilt switch turns off.The experiment adopts the principle of using analog value to regulate light brightness. So the brightness of two LEDs in the experiment will make a change. The ball tilt switch provides digital signal to trigger analog value regulation, after programming, you can see the magical light effect of these two LEDs.

=== Lesson 18: LM35 Temperature Sensor ===

'''Description''' <br>
LM35 is a common use temperature sensor. Using a LM35 and an analog port can detect the current temperature. The output voltage has linear relationship with the Celsius scale. For example, when temperature is 0 ℃, it outputs 0V; if increasing 1 ℃, the output voltage will increase 10 mv. Input its output voltage into P2 on micro:bit main board, after formula computing, display the temperature value of current surroundings on the serial monitor. In this way, we will use a serial communication software, Arduino IDE. <br>
Notice the wiring direction of LM35, or else it will damage the LM35 sensor if reversed.
