Learn what the littleBits w30 Bluetooth Low Energy Bit does, how to pair it with the Gizmos and Gadgets app, and step-by-step project ideas for wireless control in STEM classrooms.
Quick Answer
The littleBits w30 BLE Bit lets you control your inventions wirelessly from a phone or tablet, making it ideal for remote-controlled vehicles, pranks, and even triggering your device's camera. Here's how to set it up and use it in your classroom.
Why the w30 BLE Bit Stands Out
Unlike many littleBits modules that require direct physical input, the w30 BLE Bit adds a wireless layer to your circuits. It uses Bluetooth Low Energy to communicate with the Gizmos and Gadgets 2nd Edition app, so you can trigger motors, buzzers, and other outputs from a distance. This opens up project possibilities like remote-controlled cars, wireless alarms, and even camera-triggered experiments.
The trade-off is that the w30 only works with the Gizmos and Gadgets 2nd Edition app—not the older littleBits app. This means you'll need to ensure your classroom devices are compatible and have the correct app installed before starting a project.
How to Use the littleBits w30 BLE Bit
- Download the Gizmos and Gadgets 2nd Edition app: On your phone or tablet, download and install the Gizmos and Gadgets 2nd Edition app from your device's app store. This is the only app that works with the w30 BLE Bit. Check that your device's operating system is compatible with the app before class.
- Build your circuit: Connect the w30 BLE Bit to a power source and then to an output module like a motor or buzzer. Make sure the bit is marked "BLE" and that you're using the correct orientation (power, input, output). Double-check that the BLE bit is placed in the input position, not output.
- Pair the BLE Bit with your device: Open the app and follow the on-screen instructions to pair your BLE Bit. This usually involves holding the bit close to your device and confirming the connection in the app. If pairing fails, move the device closer and ensure Bluetooth is enabled on your tablet.
- Control your invention: Use the app's interface to send signals to your circuit. You can trigger motors to spin, buzzers to sound, or even use your circuit to control your device's camera. Experiment with different input modules to create more complex interactions. Start with a simple motor to confirm the wireless link works before adding more components.
