micro:bit Numeric

Kirim data numerik ke mikro: perangkat bit (koneksi bluetooth)

This app communicates between Android and a micro:bit device. You can transmit numeric data as text or value. The UART communication also has to be implemented at the micro:bit device.

Text enabled: text data transmission

Text disabled: numeric data transmission

Newline enabled: '\n' (newline) added

Newline disabled: no additional data

Zero enabled (Touch/Sense enabled): Send 0 on release button

For PXT programming you have to enable Text and Newline.

Requirements:

- Min. Android 4.4

- Bluetooth Low Energy (BLE)

- Paired devices !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

- micro:bit programm (developed by yourself)

PXT javascript example:

let str = ""

let connected = 0

input.onButtonPressed(Button.A, () => {

if (connected) {

bluetooth.uartWriteString("A")

}

})

bluetooth.onBluetoothConnected(() => {

connected = 1

})

bluetooth.onBluetoothDisconnected(() => {

connected = 0

})

bluetooth.startUartService()

basic.forever(() => {

if (connected == 1) {

str = bluetooth.uartReadUntil(serial.delimiters(Delimiters.NewLine))

if (str == "B") {

basic.showString("Hi")

} else {

basic.showString(str)

}

} else {

basic.showLeds(`

. . . . .

. # . # .

. . . . .

# . . . #

. # . # .

`)

}

})

Remark: Do not forget to pair devices (after micro:bit program changes)
