In this lesson, we use OSOYOO mini bricks to make a table tennis game machine(Ping Pong ball table).

  1. OSOYOO UNO Board (Fully compatible with Arduino UNO rev.3) x 1
  2. OSOYOO Magic I/O Shield for Arduino x 1
  3. OSOYOO Button Switch module x 2
  4. SG90 Servo motor x 2
  5. OSOYOO 3-Pin PnP cable x2
  6. USB Cable x 1
  7. PC x 1

Build Blocks:
积木搭建方法参考下面文件,但是取消microbit 及其支架,改装uno 版支架。

Wire Connection:

Firstly, please plug Osoyoo Magic I/O shield into UNO board as following:

Then plug the Potentiometer module to A0 port , plug base  servo to D9 port, plug crane servo to D8, Plug button switch to D2 of the Magic I/O shield with   3-pin PNP cables as following:

Step 1) If you haven’t install mBlock software in your PC, please read Lesson 1, download and install the software.
Step 2) Run the mBlock PC software by double click the lovely Panda icon.   Drag and Drop osoyoo_uno_mext file(downloaded in Step 1) to mBlock software as following:

Now you will see a new device firmware in mBlock, see following picture:

Now mBlock software and OSOYOO_UNO device firmware have been successfully installed in our PC!

Now we will show you how to use blocks to turn above idea into reality.
Step 1: Click Control, then Drag and drop Forever block to programming area as following:

Step 2: Click Events,   add when Arduino Uno starts up block to the top:

省略中间过程。。。

Now we have completed the block programming.  The final blocks look like following:


 Upload the program to Arduino

1)you need click the Connect button in the bottom of the mBlock software, you will see a USB window pop up,
2) select Show  all connectable device check box , then a device drop-down menu will show up,
3) select your Arduino port from device drop-down menu
4) click Connect button to  connect your PC to Arduino

5)After you PC is connected to Arduino UNO board,  please click Upload button in the bottom of your software, then the code will be uploaded to Arduino UNO board:

Test the program:

1)Put a ping pang ball inside the table and turn on the   power.
2)When you press the two button switches , the two servo rackets will move to play the ping pang ball.
