If you'd like to adjust the LED lights in your EXPLORER iPad booth, without using the Landmark app, you will need to download the Bluefruit Connect app. It is available on Android, iPhones, and iPads. It may be easier to control the LEDs using your phone (since you don't have to minimize whatever software you're using on the iPad to adjust the LEDs), but if you move the phone away from the EXPLORER booth it may lose connection to the LED controller which will reset the LEDs to their default setting. Because of this we recommend you use the Bluefruit Connect app on the iPad in the EXPLORER booth.


Download the Bluefruit Connect app to your chosen device.

Make sure the LED lights are on in the EXPLORER, and run Bluefruit Connect (Bluetooth must be enabled in your device).


When you open Bluefruit, you will be presented with this screen:

The device you want to connect to will be named CIRCUITPYxxxx (the xs being different for each controller).

Tap CONNECT to the right of the controller name.


After connecting you'll see a Modules screen:

Tap the Controller option.


There are several options in the next screen, but you can only use the bottom two: Control Pad and Color Picker


Tap Control Pad and you'll be presented with these buttons:

  • Up, Down, and Left are pre-programmed image patterns (cannot be changed)
  • Right will set the LEDs to 100% brightness with white color. It will stay at this brightness for 10 seconds before reverting to the default white setting at 50% brightness. It cannot stay at 100% brightness for more than 10 seconds or the controller will become extremely hot and may damage itself.
  • 1, 2, and are different solid color patterns. The color and brightness can be changed in the Color Picker (step 7).
    • is a steady solid color
    • is a running pattern (appears to move along the LED strip)
    • is a pulsing pattern (pulse speed cannot be changed)
  • is a running rainbow pattern (cannot be changed)


Go back to the Controller screen and select Color Picker. The setting here will affect buttons 1, 2, and in the Control Pad. I suggest you select one of those buttons before going to the Color Picker so you can see them update easily.

  • The color wheel will adjust the color
  • The top slider will adjust saturation
  • The bottom slider will adjust brightness (max 70%)

Adjust the settings to your liking, then press the SELECT button.

If you want the LEDs to be as bright as possible with a constant brightness for the whole event, select button 1 in the Controller, then set the saturation and brightness to the far left in the Color Picker (color doesn't matter). This will set the color to white and the brightness to 70% for the duration of the event (as long as the power isn't shut off and the Bluetooth device does not go out of range of the controller).

That's it! You should now be able to control the LEDs on your EXPLORER booth independent of the Landmark software.
