Ep2-2: Tutorials : ท่องโลกไปกับบทช่วยสอน

               การเรียนเขียนโปรแกรมภาษาใหม่ ๆ ต้องใช้เวลามากพอสมควร การลดระยะเวลาของการทำความเข้าใจ จึงเป็นการเพิ่มประสิทธิภาพของการเรียนรู้ ดังนั้นระบบใหม่ ๆ หรือภาษาใหม่ มักจะมีการทำ Tutorials  ออกมาเพื่ออำนวยความสะดวกและเพิ่มประสิทธิภาพการเรียนรู้สำหรับผู้เริ่มต้นเขียนโปรแกรม โดย Tutorial ส่วนมากจะเป็น tutorial ที่มีคุณภาพ ดังนั้นการศึกษาจาก Tutorial นั้น ถือว่าเป็นวิธีการเรียนรู้อย่างฉลาดวิธีหนึ่ง

👻 ในคาบเรียนนี้ เราจะมาท่อง Tutorials กัน โดยจะให้นักเรียนทำกิจกรรมอย่างน้อย 4 กิจกรรม

เข้าในห้องนี้เลยครับ https://makecode.microbit.org/

Name Tag

See your name in 💡 lights! 💡 Code the micro:bit to scroll your name across the screen.

1. Click on the  Basic category in the Toolbox. Drag the  show string block into the forever block. Then in the show string block, change the text from "Hello!" to your name.

2. Look at the micro:bit on the screen. Do you see your name scrolling across?  ⭐Great job!⭐ You've turned the micro:bit into a digital name tag!

3. If you have a micro:bit device, connect it to your computer and  click the  Download button. Follow the instructions to transfer your code onto the micro:bit and watch your name appear in lights!

4. Go further - try adding more show string blocks to create a story!

Dice

Let's create some digital 🎲  dice 🎲 with or micro:bit!

1. The on shake block runs code when you shake  👋 the micro:bit. From the Basic category, get a show number block and place it inside the on shake block to display a number.

2. Press the white SHAKE button on the micro:bit on-screen simulator, or move your cursor quickly back and forth over the simulator. Do you see the number 0 appear?  ⭐Great job!⭐

3. But we don't want to show 0 on our dice all the time. From the Math Toolbox category, drag a pick random block and drop it into the show number block replacing the 0.

4. A typical dice show values from 1 to 6 dots. So, int the pick random block, change the minimum value to 1 and the maximum value to 6.

5. Press the white SHAKE button again on the micro:bit simulator. Do you see random numbers between 1 and 6 appear?  ⭐Great job!⭐

6. If you have a micro:bit device, connect it to your computer and click the Download button. Foolow the instructions to transfer your code onto the micro:bit. Once your code has been downloaded, attach your micro:bit to battery pack and use it as digital 🎲 dice for your next boardgame!

Micro Chat

Use the micro:bit  📻 radio to send and receive 💬 massages between micro:bits!

1. From the 📶 radio Toolbox category, drag a 📶  radio set group block into the on start block. This will act as the channel over which we'll send messages. Only micro:bits who are in the group will be able to send and receive messages between them.

2. From the Input Toolbox category, drag an on button A pressed  block onto the Workspace.

3. From the 📶 radio category, drag a 📶  radio send string block into the  on button A pressed block and type a message.  When we press button A on our micro:bit, we'll send the message to every micro:bit nearby in group 1.

4. From the 📶 radio category, drag an 📶  on radio received string  block onto the Workspace.

5. Form the Basic category, get a show string block and drop it in the on radio received string block.

6. Pull the receivedString variable block out of the on received string block and put it into the show string block replacing "Hello!"

7. Let's test our code! In the micro:bit on-screen simulator, press button A. You should see a second micro:bit appear. Now try pressing A again. Do you see your message appear on the second micro:bit? ⭐Great job!⭐

8. If you have a micro:bit device, connect it to your computer and click the Download button. Follow the instructions to transfer your code onto the micro:bit. If you have two micro:bits, download the program to each one. Press button A on one and see if the other gets the message!

9. Go further - try using different buttons to send a mix of messages 📄, or send secret 🔒 messages to different radio groups!
