Grove Beginner Kit for Arduino
The Grove Beginner Kit for Arduino is one of the best kits for beginners to
get started with Arduino. No troublesome soldering and no complicated
wiring. You can focus on learning Arduino. This kit includes a main control
board, which is the Seeeduino Lotus and 8 Grove modules, covering
sensors, actuators and displays. All you need to do is follow the tutorials,
plug the modules into the Seeeduino Lotus and build your cool projects.
Seeeduino Lotus v1.1
Grove - Tilt Switch
Grove - Buzzer
Grove - Temperature & Humidity Sensor (DHT11)
Grove - 3-Axis Digital Accelerometer(±1.5g)
Grove - Light Sensor v1.2
Grove - Line Finder v1.1
Grove – Chainable RGB LED V2.0
Grove - 16 x 2 LCD (White on Blue)
About Grove
Before we had Grove, at least three wires were needed every time a
module had to be connected to an Arduino, including power, signal, and
ground. So, Arduino was quite hard to manipulate among excessive
wires.
Parts List:

If this is your first time using a Seeeduino Lotus along with the Grove
modules, don’t worry, we got you covered! We have a detailed
step-by-step tutorial to guide you through. Find it in the "Getting
Started” section of the Grove - Beginner Kit's wiki page:
Also, we have made an interesting video for this kit, and it will help you
to get started quickly and easily!
Follow this link for the video:
How could we simplify this building process? Well…. Grove Ecosystem is
the solution. Every Grove module has a function, such as sensing light,
sensing motion. Also, you only need one Grove cable to connect between
these modules and the Seeeduino Lotus for the modules to function
reliably in your design.

Sketchbook Download
After following the “Getting Started” section, if you succeed in blinking
the built-in LED, you can start to tinker with the Grove Beginner Kit for
Arduino. To simplify the coding tasks for you, we packed a few demos of
Grove Beginner Kit into a sketchbook file and uploaded it into GitHub.
Here is the link to download it:

There are four kind of Grove cables for different needs. For general
projects using Seeeduino or Base Shield, you can simply use the
standard cables. For projects where you need to connect two I2C devices
by connecting the Grove cable to the I2C port of the main board, you can
use the branch cables. If your project uses two servos, you can choose
Grove – Branch Cable for Servo. If you don’t want to use a Base Shield
or a Seeeduino in your projects, you can choose Grove to 4pin
Female/Male Jumpers, with which you can connect Grove module to
your breadboard directly. Each kind of cable have five different sizes of
length, 5cm, 20cm, 30cm, 40cm, and 50cm.

The Buzzer can give you interesting sound effects and you
will find it fun to play with.
Tips
The sound frequency of this Buzzer will change according to the change
in shaking frequency set from the Arduino IDE
Example
You can use the codes included to make the buzzer beep.
However, Grove-Buzzer can be much more fun. It can play
melodies! Find the examples via the path below:

This switch will turn on and off according to the orienta-
tion you hold it.
Example
You can use the codes included in order to
switch on or off the built-in LED on the Seeeduino Lotus
just by tilting this up or down. Find this example and
more via the path below:

Tips
Inside this tilt switch is a pair of balls that make contact with the pins
when the case is upright and thus making a connection.

Tips
The sound frequency of this Buzzer will change according to the change
in shaking frequency set from the Arduino IDE

This RGB LED will allow you to light up your projects by
chaining 1024 RGB LEDs at most!
Example
You can use the codes included to make the LED react
according to your commands. You will find it fun to use
with vivid and magical light effects. Find this example

You can measure different intensities of light using this
sensor and let it react accordingly.
Example
You can use the codes included to react according to the
ambient light and turn on the Grove – Chainable RGB
LED. We have also provided another example. Find them

Tips
The resistance of the photo-resistor on this module decreases when
the light intensity increases and vice versa, thus output accordingly.

You can use this module in your next robotics projects for
robots to follow a drawn path!
Example
You can use the codes included to turn on and off the Grove
– Chainable LED, based on the position of the Line Finder.
Also, there are two other examples we have included.
