This example show how to connect the arduino to mblock(actually,it is scratch 2.0).
I used one arduino UNO and one joystick.the H/W connection like below <picture 1>.
please pay attation, I connect the joystick VCC to 3.3V not 5V.
than connected the USB to computuer usb port.
<Picture 1> Arduino UNO+ Joystick
<Picture 2> after connecting the arduino uno to PC USB port,you can check which serial port be used in your computer.
<Picture 3>Opem mblock to select the serial port which in your PC device manager<Picture 2> .Here is COM5.
<Picture 4> Select Arduino UNO board.IF you use other Arduino board like as Mega or nano.just select which board you used.
<Picture 5> select Arduino.
<Picture 6> Select <firmware update> ,it will auto download the arduino firmware to your arduino board. After download firmware then compeleted the connecting between arduino and mblock.
<Picture 7 >You can see one more block <Robots> .You can use it to progarm your arduino board.
<Picture 8> Below is my sample code for joystick.
