I have a list of around 1000+ churches that contains the name of the church, simple address, the residing priest and some contains mass schedules. I thought it will be nice if we can get the latitude and longitude based on the given address.

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:

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 pressing the switch. If the color you’ve chosen matches the color that the accessory generated then you win the game.

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.
