What is an Arduino?

This is for those who do not know what is an Arduino!

  • The Arduino is the largest open-source hardware platform based on easy to use hardware and software
  • Arduino boards are able to read inputs like a finger on a button and turn it into an output which in turn, for example, activate a motor which you can change by sending a set of instructions through Arduino programming language or their Arduino Software (IDE)
  • Due to its simplicity, it has become many makers, students and beginners go-to hardware for many projects and applications from complex scientific instruments to everyday objects.
  • Thus, if you want to start on electronics or programming, an Arduino will be your best pick.
  • Here at Seeed, we offer various Arduino Boards like the Arduino Uno Rev3 , Arduino Nano v3 and many more! Interested? Check out all our Arduino boards here.

Without further ado, let us jump right in to what is inside our Arduino Kits!

What is inside our Grove beginner and starter kits for Arduino?

Before we move on, you may be wondering, what is Grove?

  • As an open source hardware facilitator, we are dedicated to make electronic prototyping easy and fast for users, and we believe that more effort should be put on concepts design rather than how to build basic circuits especially in the idea phase. That is why we created Grove.
  • Well, Grove is Seeed’s very own modular electronic platform for quick prototyping. Every module has one function, such as touch sensing, creating audio effect, etc.
  • Many configurations can be assembled without the need for soldering or breadboarding. Just plug in the modules, and you are ready to go!
  • Our standardised Grove connector allows user to assemble Grove units with building block approach, compared to the jumper or solder based system, it is much easier to assemble or disassemble, which simplifies the learning system for experimenting, building and prototyping.

Inside the Grove Beginner Kit for Arduino ($29.90)

We believe that with the help of this Grove Beginner Kit for Arduino, no matter you’re a student, teacher, maker, hobbyist, etc. we believe it will gear you up to know the Arduino quickly and comprehensively.

It contains 1 Development board and 8 Grove modules:

Seeeduino Lotus V1.1

  • This is probably the board that catches your attention first and the most important piece of the kit – The Seeeduino Lotus V1.1.
  • It is a development board with ATMEGA328 AVR microcontroller, which is the combination of Seeeduino and Grove Base Shield.
  • It uses an Atmel ATmege328-MU microcontroller and CP2102N chip
    • ATmege328-MU is a high performance, low power AVR 8-bit Microcontroller while CP2102N is a USB to Serial converter chip which allows you to communicate the Seeeduino Lotus with computer by using a micro-USB cable.
  • Seeeduino Lotus has 14 Digital input/output(6 can be used as PWM outputs) and 7 Analog input/output, a micro USB connection, an ICSP header, 12 Grove connector, a reset button and it is fully compatible with Arduino UNO.

Grove – Buzzer

  • As the name refers, this is a piezo buzzer. It is able to produce a high pitch tone while it is connected to digital output and logic level is set to high.
  • You can also control the various tones according to the frequencies generated from the analog PWM output that is connected to it

Grove – Tilt Switch

  • The tilt switch, is like a button and used as a digital input.
  • It contains a pair of balls that make contact with the pins when the case is upright. If the case is tilted, the balls would not touch and no connection would happen
  • It is wired to the SIG line, NC is not used on this Grove module.

Grove – Chainable RGB LED

  • This is a LED module where you can bring vivid light effects into your projects!
  • LEDs are hard to connect together, however, with our Chainable RGB LED, it simplifies everything with its
     2-wire transmission which can be used to cascade additional Grove – Chainable RGB LED modules!
  • It is based on a P9813 chip which is a full-color LED driver and provides 3 constant-current drivers as well as modulated output of 256 shades of gray!

Grove – Light Sensor

  • As the name states, it is a light sensor which is aimed at measuring the intensity of light levels using a photo-resistor.
  • It works by as the intensity of light decreases, the resistance of the photo-resistor also decreases where a dual OpAmp chip LM358 on board will produce voltage corresponding to intensity of light(i.e. based on resistance value).
  • The output signal is analog value, the brighter the light is, the larger the value.

Grove – Line Finder

  • With this module, you can build your own line-following robot!
  • Those eye-like sensors on the board are actually IR emitting LED and sensitive phototransistor.
    • When the phototransistor detects the reflected infrared light from the IR emitting LED, it will output a digital signal, which changes from high to low to the Arduino so that the robot can follow a black line on white background, or vice versa.

Grove – LCD RGB Backlight

  • This LCD RB Backlight acts as a perfect I2C LCD display for your Arduino with its high contrast and simplicity!
  • As it uses I2C interface to communicate with the Arduino,
    it will reduce the pin header from 10 to 2 which is very convenient for the Grove system.
  • Not only can it display characters, it can also display DIY images like a heart symbol or stick-man on this LCD module through a simple coding configuration.
  • In addition, it has an RGB backlight which means you can set any colour you like to be the backlight.

Grove – 16×2 LCD (White on Blue)

  • Except for RGB backlights, this LCD is almost identical to the Grove – LCD RGB Backlight, they are all 16 characters wide, 2 rows with high brightness backlight

Grove – Temperature & Humidity Sensor(DHT11)

  • This sensor is a high quality digital temperature and humidity sensor based on the new DHT11 which provides a pre-calibrated digital output
  • It features low power consumption, long-term stability and excellent reliability which makes it perfect for your temperature and humidity measurement needs.
  • A unique capacitive sensor element is used to measure relative humidity while temperature is measured by a negative temperature coefficient (NTC) thermistor.

Grove – 3-Axis Digital Accelerometer

  • The 3-Axis Digital Accelerometer plays a big part in projects like orientation detection, gesture detection and Motion detection.
  • They are used for sensing data changes, product orientation, and gesture detection through an interrupt pin (INT).
  • Based on Freescale’s low power consumption module, MMA7660FC, it is a very low power, low profile capacitive MEMS sensor and features up to 10,000g high shock survivability and configurable Samples per Second rate.

10 Grove Cables

  • We also provided 10 grove cables in the kit for you to be able to combine all the modules and sensors and use them together with the Arduino.

Now you know each module functions inside the Grove Beginner Kit, what can you do with it?
