The OSOYOO building bricks is mechanically compatible with leading building bricks. In this lesson, we will use OSOYOO Bricks to build an Trebuchet which can throw a Ping Pang ball.
Firstly, please plug Osoyoo Magic I/O shield into UNO board as following：
Secondly, Connect wires as per following picture:
Motor Fan to L1
Button to D2 port
Servo to D9 port
Finally, use the USB cable to connect your PC to the OSOYOO UNO board
Step 1) Download mBlock PChttps://mblock.makeblock.com/en-us/download/, select the download file as per your computer OS type:
Step 2)Download OSOYOO_UNO.mext device file from https://osoyoo.com/driver/mblock/osoyoo_uno.mext
Step 3) Run the mBlock PC software by double click the lovely Panda icon. you will see mBlock UI as following picture. Please delete the default device CyberPi by click the cross in the red circle.
Step 4: Drag and Drop osoyoo_uno_mext file(downloaded in Step 2) 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 make our Oscillating Pedestal Fan 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:
Step 3: Click Control , drag if else block to forever loop,
Step 4: Click Sensor, Add Button Pressed blocks to if condition area, change Pin number to 2:
Step 5) Click Action , then drag set Servo Pin blocks to if else block as following:
Now all the programming blocks have been completed! From above picture, the logic is pretty straightforward:
When Arduino is started, computer will enter a dead loop which will check the button status, when button is not pressed, the servo will stop at original position (in my servo 60 degree ) , when button is pressed, the servo arm will rotate from 60 degree position to 30 degree position and push the ball out of the track.
1)you need connect your Arduino board to your PC with a USB cable first. Then 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:
Now turn on the power switch in the Magic board, the Arduino will start to work. Press the button on D2, your servo arm will push the ball out of the track, when you release the button, the servo arm will go back to its original position.
