Arduino 101 Scratch Extension

Getting Started

Upload the firmware to the Arduino board

The board will remember the firmware so you will only have to complete this step once.

  1. If you haven't already, download and install the Arduino IDE (Windows or Mac instructions)
  2. Connect the Arduino/Genuino 101 board to your computer's USB port
  3. Launch the Arduino IDE
  4. Click on the Tools menu and select Board > Boards Manager...
  5. Search for "curie" and install the Intel Curie Boards by Intel. Close the Boards Manager once the installation is complete.
  6. Download the custom Arduino 101 firmware and open it in the Arduino IDE
  7. Select Arduino/Genuino 101 under the Tools > Board menu
  8. Select the correct serial port under the Tools > Port menu.
    On Mac, it's something like /dev/cu.usbmodemXXXXX.
    On Windows, it's probably the highest-numbered COM port.
    (Or unplug the Arduino, check the menu, and then replug your Arduino and see what new port appears.)
  9. Click the upload button
