Whether you are a newbie or an expert at programming/ electronics and want unleash your creativity though microprocessor programming, Arduino is just the perfect platform for you to kick off. This mini wonder is a micro-controller which is nothing but a small computer that you can control to perform various functions . E.g Turing LED lamp on/off . Hold on! You may wonder "why would I need a 'computer' to turn on a LED ? I can do it with a switch !" Consider this - you want a LED to blink after every 1 minute, or a more complex situation of a traffic signal, where multiple LED lamps need to turn on/off periodically....... or even more difficult situation where the traffic varies a lot. Now Green signal needs to be kept on in proportion to the traffic in that lane. It means, traffic in all lanes needs to be sensed to control the traffic light all the time. These problems cannot be solved by a mere switch. Only a computer. Can perform...
