Android app development Kit for Starters

Android is a great platform to start building your apps, but its not the simplest to start with. For that reason we at hobbyist have built a kit which will take you through the process of building an App step by step. We start with the bare basics and eventually take you into building an app which does some fancy home automation for you.

  It covers the basics of app development and then delves into using bluetooth wireless to talk to Arduino platform. This paves way for reading remote sensor data from the Android tablet and use it as a dashboard for home automation and doing remote robot control.

What you can accomplish with this kit :

  • Learn the basics of Android App development
  • Simple Hello World App
  • Make the app talk to an Arduino

           * Then read the moisture and temp of your garden

  • Read data from Arduino and turn ON devices with touch of a button.

           * Now you can turn on Lamps, Tv's, Heaters right from the app

  • Send a message wirelessly to an OLED display via the app

           * Make this your message board & leave messages to family & flatmates

Kit Contains

  • OLED Display
  • 1 Arduino
  • Temp & Humidity Sensor
  • Single Channel Relay
  • Bluetooth Module
  • BreadBoard and connector wires
  • Software tutorial and code

Other parts needed but not included:

  • An Android (3.0 or later) mobile/tablet with Bluetooth

Home Insulation Meter


How good is my home insulation?

With this Home Insulation Meter, you can have a fairly good idea of how well your home insulation is working for you. Knowing the insulation performence allows you to make informed decisions on improving/investing your home.

How does it work?

This Home Insulation Meter has two precision temperature sensors, one is external with a 1.2 m cable, and the other one is internal in the box. By locating the two temperature sensors in two different areas (e.g. indoor and under floor), Home Insulation Meter will measure and log the temeperatures to a SD card. The temperature variation of the two areas can then be plotted and analysed.

No need to open up the box to retrieve the data, this Home Insulation Meter allows you to retrieve its data wirelessly via Bluetooth.

This Home Insulation meter embodies a few very cool technologies: Real Time Clock, SD Card read/write, Bluetooth and one wire digital temperature sensor. It can be easily turned into a general purpose wireless sensor logger. It is also a fantastic educational kit after all.

What is included in this kit?

This kit includes all the neccessary bits to construct a fully working Home Insulation Meter, the package includes:

  • Arduino Mega 2560
  • Arduino Mega sensor and servo shield
  • USB cable
  • Real Time Clock module (onboard temperature sensor incl.)
  • SD card module
  • Kingston SD Card 1 GB
  • Bluetooth module
  • Temperature sensor
  • Waterproof case
  • Cable gland x 2
  • Some wires and accessories

Follow this 3-step tutorial to assemble this amazing kit.

Step 1: Interfacing Real Time Clock and Temperature sensor to Arduino Mega

Step 2: Interfacing SD Card Module to Arduino Mega

Step 3: Interfacing Bluetooth Module to Arduino Mega

Bluetooth Mars Rover Robotic Kit


Want to wirelessly control a Mars rover from your laptop?

You are in the right place, this kit does exactly that. 10 minutes is what it takes to wire up the electronics, it doesn't even need soldering. For people who know programming, this kit is more than a remote control robot.

You can write program on your pc to communicate with the robot such as scheduling tasks and receiving sensor data (e.g. video, image, switch, temperature, light etc) from the robot. You can even control the robot on the internet!! The ways it can be used are endless...

This kit includes

  1. Mars Rover
  2. Arduino Duemilanove 2009
  3. Motor shield
  4. Bluetooth module
  5. 4-way stripped wires and approx. 10 breadboard wires

All you need to add is 6 AA batteries, and a laptop with Bluetooth connectivity.

The Mars rover platform is a robust and easily adjustable track drive chassis that is perfect for robotics hobbyists. It has two DC motor built-in, and it's already assembled. A 6-slot battery case is also included. The height of the track wheels are manually adjustable.

Tutorials provided at the bottom of this page show you how to assemble it, and the available open source code demonstrates how to control the rover on the keyboard. 'e', 'c', 's', 'f', 'd' keys command the robot to go forward, backward, left, right and stop.

Specs provided by the manufacturer:

  • Dimensions: 245mm length x 225mm width x 74mm height
  • Adjustable height: 74mm-100mm
  • Ground clearance: 21mm-50mm
  • Operating voltage: 7.2V
  • Operating current: 160–180 mA
  • Maximum speed: 30 cm/s(speed can reach 42cm/s at 12 V)
  • Maximum climbing angle: > 30°
  • Maximum payload: > 7.5Kg

Note: the specs above should only used be as a reference, performance of individual platform may vary due to manufacturing tolerance, battery type and operating conditions.



Please see our 3-step tutorial on how to make a bluetooth robot:

Step1, hook up the Motor Shield

Step2, test the Bluetooth module

Step3, combine Bluetooth with Motor Shield
