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 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 upblock to the top:
Step 3: Click Control, add if thenblock inside forever block:
Step 4: Click Operator category, then add < 50 block into if else block condition area, change the value from 50 to 15 as following:
Step 5: Click Sensor category, add read ultrasonic sensor block into <15 block, change trig pin to 7 , echo pin to 8 as following:
Step 6: Click Action category, add two pcs set servo pin blocks into if else block, change angle as value to 20 and 90 as following:
Now we have completed the block programming. The final blocks look like following:
Upload the program to OSOYOO basic board.

When your car arrives the gate front and is detected by ultrasonic sensor, the gate will open. When the car passes the gate, the gate will close automatically.
In this lesson, we use OSOYOO mini bricks to make a smart garage gate. When Ultrasonic detect a car, the gate will open automatically.
