First off, I am completely new to the Arduino "world".
I see this little "slice of technology" can be used in many various applications. My project : Can it be used along with 4 push button-switches as a type of "digital lock" where as a correct 4-button sequence has to entered to open or close a relay ?
Again, I am totally new and have no idea on how to build, program ( if needed ) a Arduino. I DO HOWEVER have 25 years plus of electronic gaming repair under my belt. So I am electronically able, just never heard of Arduino until now.
What is needed ? Do I need to program this thing ? I can read schematics which would also be a BIG help.
Thank you, I am really interested in building some projects using Arduino.
