Before we can use the IDE to upload the firmware to the Mini RAMBo controller, we need to tell the Arduino IDE what kind of board we have and what communications port it needs to use in order to perform the upload task.

Click on the “Tools” menu item and then click on “Board” and then “Arduino Mega or Mega 2560”.

Click on the “Tools” menu item and then click on “Processor” and then “AT Mega (Mega 2560)”.

Next, you'll need to tell the Arduino IDE what port to talk to the RAMBo on. To do this, click on “Tools”, “Serial Port” and then choose the COM port that your RAMBo appears as on your computer. (you can find this in the device manager)
