User Manual

1.Grove Shield for micro:bit
Because micro:bit does not have the
Grove interface, the Grove Shield for
micro:bit adds 4 grove interfaces. This
allows Grove modules to connect to the
Grove shield and communicate with
micro:bit.
2.Grove - Rotary Angle Sensor (P)
There is a 10kΩ potentiometer in the
sensor, when you rotate the rotary knob,
the value of this potentiometer will
change. This causes the output signal to
change linearly based on the angle
(0˚~300˚). You can use this rotary knob
to control volume, speed, or any other
variable!
3.Grove – Speaker
The speaker can emit a variety of
sounds such as a car horn, a doorbell,
and an alarm. By changing the frequen-
cy of the input signal, you will get
different sounds. You can also adjust
the loudness by changing the angle of
the cross screw.
4.Grove – Ultrasonic Ranger
This sensor sends out an ultrasonic
sound. Based on when (or if) the sound
returns to the sensor it can tell how far
away an object is. This can be used to
build projects that output different
effects such as lights or sounds by
changes in distance.
7.Grove – Gesture
This gesture sensor can recognize 9
different gestures: left, right, up, down,
forwards, backwards, clockwise rotation,
counter-clockwise rotation, and waving. You
can use this sensor to build very fun applica-
tions such as using your gestures to switch
songs or adjust the music volume.
8.Grove - 4-Digit Display
This display is very suitable for
displaying numbers. It can be used to
display time, distance, or display other
sensor’s values.
5.Grove – Light Sensor V1.2
The light sensor is used to detect how
much bright light is. This sensor is a
photo-resistor which controls the
current. Based on how much light the
senor detects, you could turn volume up
or down, sound an alarm, or increase
how fast an LED blinks!
6.Grove - WS2812 Waterproof LED
Strip - 30 LEDs 1 meter
This is a RGB LED strip. RGB means
each LED can change colors and You
can control each LED separately to
show different colors. It is also water-
proof so you are free to use it outdoor
without worrying about rain.
9.Grove - Red LED
This is a simple red LED. The
maximum brightness can be
controlled by the onboard potentiom-
eter that integrates grove interface.
Grove Starter Kit for micro:bit

Note
Some projects with more than 1 Grove modules demands
relatively more current, in order to make those Groves
function better, we recommend using the USB port on Grove
Shield for micro:bit to power the circuit.
