Introduction to UART Write Number
The UART Write Number feature allows the micro:bit to send numerical data to a Bluetooth-connected device, such as a smartphone. This is part of the Bluetooth UART service, which enables seamless data exchange between the micro:bit and other devices. To utilize this feature, the micro:bit must first be paired with the device. Once connected, you can use the command bluetooth.uartWriteNumber(42); to send the number 42 to the connected device. This functionality is particularly useful for applications that require real-time data transmission, such as remote monitoring or control systems.
Key Features:
- Bluetooth Connectivity: Easily connect to smartphones and other Bluetooth-enabled devices.
- Data Exchange: Send and receive numerical data in real-time.
- Simple Command: Use straightforward commands to transmit data.
Use Cases:
- Remote Monitoring: Send sensor data to a mobile app for monitoring.
- Control Systems: Use the micro:bit to control devices based on numerical inputs from a smartphone.
