Last week I decided to buy some stuff from local reseller of Arduino. I bought a Kyto Heart Sensor that transmits heart pulses to a receiver via radio frequency. The RF receiver can then be interfaced to an arduino and then pass the results to an Android device for visualization.

If you’ll try to create a sketch using the Android ADK library on  the latest version of Arduino (1.0 as of this writing), you will get several errors just like this:

This is because they renamed some header files and also changed the signature of some commonly used functions. Initially I thought it will take [...]

So I’ve made a little not-so-challenging game that uses a tricolor LED, mini buzzer, arduino and of course our Android device. The mechanics of the game is that you need to choose a color, red, green or blue from the Android app and then the accessory (arduino) will randomly pick a color after [...]

In this post, I’ll show you how to use a micro-servo in Arduino and be controlled from an Android application. Let’s start by describing what a servo is.

A servomotor is a motor in which the shaft rotates in micro steps. You can control the servo by sending the angular degrees by which it [...]

Today, I’m going to show how easy it is to read data from an accessory to your android device. In this example, we are going to use a special kind of resistor whose resistance is dependent on the amount of light falling on its surface. It is called Light-Dependent-Resistor or LDR or also known [...]

Writing applications on Android is cool but writing applications on Android that can talk to the physical world is totally awesome. I recently bought a Seeduino ADK Board, which is actually a clone of an Arduino board that has support for the Android Accessory Development Kit. You can find more information about Seeduino here.
