Good arduino projects require documentation.
Free documentation is even better !

Manual and Automatic Traffic Lights
And something else, which we'll start with before trying to regulate our traffic.
We'll use LEDs (Light Emitting Diode): 1 red, 1 yellow and... ?!?!
yes, 1 green.
In the first part every LED will be gradually turned from off to on and viceversa.
After that, the traffic lights: just one LED on.
We need following stuff:

Capacitor on breadboard
One classical example to take confidence in electronic circuits is related to charging/discharging capacitors (symbol: C).
These components are able to catch electrical charges and to keep them for a long time; theoretically for an infinite one, but this is impossible, first of all because of Joule effect (heat dissipation to the ambient with slow progressive energy loosing).
