Projekt -Policijska sirena i oznaka Starta
Pritiskom na prvo(vanjsko) tipkalo crvena i plava led dioda počinju titrati i zvučati kao prava policijska sirena. Ako se pritisne drugo tipkalo(unutarnje) crvena i zelena led dioda počinju svijetliti u obliku starta na trkaćim stazama.

Spojene su tri diode i dva tipkala i dva senzora za zvuk na Arduino mikrokontroler i eksperimentalnu pločicu.
