A month ago I knew nothing about Arduino and now.....my first project!
Looking back, this project combines allmost all of the tutorials that I have read in this short period: blinking LED, push button, piezo and LCD display. A useful project for every beginner!
I have made this device for some of my friends who have a hard time admitting how fast alcohol influences their driving abilities.
It will test you on three levels because they all have to do with driving a car safely:
Resistance to DISTRACTION.
The test starts as soon as you hold down the push button. When a red light appears, you should let go off the push button as soon as possible. Your reaction time will appear on the screen.
However, driving has to do with making fast decisions as well. So in random order you can get a green or blue light first (or multiples). You should not react to this and hold down the push button until
the red light appears.
Finally, on occasions you will hear a short beep in between lights (just for fun). By now you are so tense to do well, that a simple distraction like a beep can and WILL set you off!!
A fun game with your dinner guests upon arrival and confronting upon leaving!
