starting with Arduino

Hello,

thank you all for response.

@raschemmel, you are right...my description is to vague.Since basically it is school demo case, for beggining my idea would be to do project in next way:

  1. As a input I would like to use motion detector sensor
  2. use UNO as receive input from sensor and as output to run 12V DC small engine based on how many motions will be in period of, for example 1 minute (I have to define frequency in UNO )

Next project I would like to use in commbination with IP router but would leave this as second step:)

@zoomkat, thx for suggestion, I have already purchase it.

Br,
Petar.
