Serial Write Numbers

Write an array of numbers to the serial port.

serial.writeNumbers([0, 1, 2]);

Instead of writing a single number at a time using write number, you can write multiple numbers to the serial port at once. They are written as Comma Separated Values (CSV).

You can write the numbers 0 through 5 together and they will appear as one line of serial output:

0,1,2,3,4,5

This makes a line of CSV data where the commas between the numbers are the separators for each value.

Parameters

  • values: the array of numbers to write to the serial port

Example: one two three

This program repeatedly writes a 3-number array to the serial port.

basic.forever(() => {
    serial.writeNumbers([1, 2, 3]);
    basic.pause(5000);
});

Example: plot temperature and light

serial.writeLine("temp,light")
basic.forever(() => {
    serial.writeNumbers([input.temperature(), input.lightLevel()])
})
