if both the iOS device and the PC that Scratch runs on are on the same Wi-Fi network and Remote Sensor Connections are enabled correctly, you should see message saying "Connected".

If Scratch2Romo is connected to Scratch, you can control Romo from Scratch.

On Scratch, click "Control" on the top left area, drag "broadcast backward" block to the center area, then right click on the block. You should see the list of the commands that can be sent to Scratch2Romo to control Romo.

What you can do with these commands is as follows:

  • forward - make Romo drive forward
  • left - make Romo turn left
  • right - make Romo turn right
