Mini project1,

­­­­­­For first mini project, I would like to show the differences and similarities between two or more words in two different languages (Persian and English). This project is along with people interaction in which not only see the translation, but also they are part of that to disclose and show the concept. 

I have a plan for interacting and showing two words with same translation, specially some words that have same letters or sort of close pronunciation, it is better to use the different color LED or even same color. Two words are overlapping, and by moving the hand one word starts to light and with second movement the second word with LED light will be on. This process is like a gradually lighting with RGB LED. Simply at first all the common letters which are the top of the word is going to be on. For this project I think I use Proximity sensor or IR distance sensors. In this project I need a sensor, which detects motion or movement, and then the output is lighting the LED.

Parts for this project is mostly similar to parts in Chapter 4 in Exploring Arduino book
