To use the Hummingbird Bit with Snap!, Python, or Java, the Bit must be connected to the computer via USB or Bluetooth.
Connecting via a USB cord requires no additional equipment. The Hummingbird controller must remain connected to the USB cord at all times to run your Snap!, Python, or Java programs. If you are using Chromebooks, you must connect via the USB cord.
For additional functionality on Windows or Mac machines, you can use the Bluetooth USB dongle. The Bluetooth dongle enables you to connect to up to three devices using Bluetooth. This means that your robots do not have to be connected to the computer with a cord. The Bluetooth dongle must be purchased in addition to the Bit Kit.
