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 turn above idea into reality. Step 1: Click Events, add when Arduino Uno starts upblock to programming area.
Step 2：Click Action, drag set servo pin 9 Angle as 90 block twice and change angle to 0 and 180 as following:
Step 4：Click Control, then Drag and drop Forever block under wait 1 seconds block as following:
Step 5:Click Control, drag if-then block to forever loop as following:
Step 6: Click Operation, drag X =50 block on the placeholder of the if-then block, and change 50 to 85 as following:
Step 7: Click Sensor, drag Read IR data from Pin 2 block on the first placeholder of the X =85 block as following:
Step 8: Click Action, drag set servo pin 9 Angle as 90 under the if-then block, and change 90 to 180 as following:
Step 9 :Click Control, then drag wait 1 seconds block, and change 1 to 0.01 as following:
Step 10: Repeat Step 5 ~ Step 8 , you will get it as following:
then change the date as following：
Step 11:Click Control, drag if-then block; Click Operation, drag X =50 block;Click Sensor, drag Read IR date from Pin 2 block as following:
then change the date as following:
Step12 :Click Action, then drag Backward Left Speed 100 Right Speed 100 block, and change 100 to 0 and 25 as following:
Step13:Click Control, drag wait 1 secondsblock and change 1 to 0.1; Click Action, drag Stop Moving as following:
Step14: Repeat Step 11 ~ Step 13 , you will get it as following:
then change the date as following:
Now we have completed the block programming. The final blocks look like following:
