Hacking STEM

Support for Hacking STEM activities in micro:bit. For Hacking Stem activities you will need excel add-on Data Streamer as well. To download Data Streamer click here

Usage

Go to https://makecode.microbit.org, click on the gearwheel menu and select Extensions, search for hacking stem and select this extension. Once you load the extension you should see a new category named DataStreamer.

Reference

dataStreamer.writeNumber

The ||dataStreamer.writeNumber|| block writes a number to the serial port as a floating point number.

dataStreamer.writeNumber(1.52, 2);

Parameters

• value is the floating point number to write to the serial port
• decimal digits is the number of decimal digits to write. Default is 2.

Example 1

For example,

dataStreamer.writeNumber(1.52);

writes the following number to serial 1.52

Example 2

This example reads the analog signal on pin P0, scales it to 3.3v and writes it to serial.

let mv = 0
basic.forever(() => {
    mv = pins.analogReadPin(AnalogPin.P0) * 3.3 / 1023
    dataStreamer.writeNumber(mv)
})

dataStreamer.writeString

The ||dataStreamer.writeString|| block writes a string to the serial port, without starting a new line afterward.

dataStreamer.writeString(",");

Parameters

• text is the string to write to the serial port

Example: simple serial

This program writes a comma , seperated 10.25 to the serial port repeatedly, without any new lines.

basic.forever(() => {
    dataStreamer.writeNumber(10.25);
    dataStreamer.writeString(",");
});
