~

Example: Two-way radio

If you load this program onto two or more @boardname@s, you can send a code word from one of them to the others by pressing button A. The other @boardname@s will receive the code word and then show it.

input.onButtonEvent(Button.A, ButtonEvent.Click, () => {
    radio.sendString("Codeword: TRIMARAN")
    basic.showString("SENT");
})
radio.onReceivedString(function (receivedString) {
    basic.showString(receivedString);
})

~hint

A radio that can both transmit and receive is called a transceiver.
