Grove Starter Kit for micro:bit
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 water­proof so you are free to use it outdoor without worrying about rain.
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.
3.Grove – Speaker
The speaker can emit a variety of sounds such as a car horn, a doorbell, and an alarm. By changing the frequen­cy of the input signal, you will get different sounds. You can also adjust the loudness by changing the angle of the cross screw.
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!
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 applications such as using your gestures to switch songs or adjust the music volume.
9.Grove - Red LED
This is a simple red LED. The maximum brightness can be controlled by the onboard potentiometer that integrates grove interface.
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.
