Hi,
trying to have my arduino UNO communicate with mBlock 5.
in arduino code : write “hello” to serial port
in sprite code : when I receive “hello” > say “Hello !” for 2 seconds
script compiles and uploads to arduino, but when message is sent nothing happens !
How can I have the sprite listen to arduino serial message ?
What can I have the sprite write to arduino serial to answer the message ?
Thanks
