Step Two:

Turn on the Bluetooth Cubelet
  • Connect the Bluetooth Cubelet with a Battery Cubelet.
  • Turn on the Battery Cubelet.
  • The Bluetooth Cubelet will begin flashing a unique three-color sequence.

EXAMPLE: A Cubelet that flashed Red-Green-Blue will appear as “Cubelet-RGB” when you pair it with a mobile device.

Step Three:

Pair With Your Device
  • On your mobile device, enter the “Settings” app.
  • Select “Bluetooth” from the menu.
  • In the list of available devices, select the Bluetooth Cubelet that corresponds with your Bluetooth Cubelet’s unique flashing color sequence. This step allows you to differentiate between multiple Bluetooth Cubelets.
  • When your Bluetooth Cubelet has successfully paired with your device, you will see the word “Connected” beside your Cubelet.

Step Four:

Build a Cubelets Robot

For this example you will need a Bluetooth Cubelet, Battery Cubelet and Drive Cubelet.

Connect all three Cubelets to build a Bluetooth Drive Robot like the one pictured to the left.

Step Five:

Remote Control
  • After you’ve paired with the Bluetooth Cubelet and built your robot, open the Cubelets app on your mobile device.
  • If you’ve paired successfully, you will see your Bluetooth Cubelet in the “Connect” window. If pairing was unsuccessful, please repeat Step Three.
  • Tap the icon of the Cubelet you want to control.
  • Select any of the Cubelets you wish to remote control.
  • Tap “Control” in the upper right corner.
  • In the control window you will see a simple slider. Tap the “Off” button at the bottom of the slider.
  • Now that your Cubelet is “On,” push the slider up to make your robot drive forward!
  • Hit the “On” button at the bottom of the slider to stop your robot quickly.
