Arduino is a Powerful pocket computer. I can help you program it to do a variety of Tasks.
Arduino can sense its environment by reading input signals from a variety of sensor like GPS, Light Sensors, Humidity Sensors, Gas Sensors, Key-pad, etc. and it can take actions like controlling Motors, Display, LED and Electronic Equipment's.
Which makes it ideal for Most of the Engineering and Hobby Projects.
Some of the Example where Arduino Can be used are :
1. A GPS Tracker to Plot your journey Co-ordinates on Google Maps. 2. An Autonomous Robot, which can find it correct path to its destination 3. Remotely Controlling your Home Equipment 4. Build a automatic pet-feeder, etc, etc....... Google Arduino to get more ideas....
