The 3-axis Digital Accelerometer is the key part in projects like orientation detection, gesture detection and Motion detection. It provides readings in x-, y-, and z-axis orientations in terms of "g"s.

The Barometer Sensor can be used to measure temperature and atmospheric pressure accurately. As the atmospheric pressure changes with altitude, it can also measure approximate altitude of a place.

The buzzer can be used to generate tones between 31Hz and 65536 Hz.

The OLED Display is an OLED monochrome 128×64dot matrix display module.

The RGB-backlit LCD screen can display text in two rows of up to 16 characters each, backlit with an RGB (red-green-blue) LED capable of displaying 16.7M individual colours.

Multiple RGBA LEDs can be chained together to create a string of colour-changing lights.

The Grove servomotor can be used to control rotary position within an 180-degree range.

The Grove Thumb Joystick is an analog device that connects to one analog port on the Grove shield but uses two analog pins on the Arduino to get X and Y components of the joystick’s movement.

The Grove Ultrasonic Ranger is a non-contact distance measurement module. It has a measuring range of 2 - 350cm, with a resolution of 1cm.
