Quote: "This setup is connected to PC via LPT port. While PC is turned OFF, yellow lights will flash. After starting the PC software, traffic lights will start operation. There is also IR remote option for this software to disable or enable intersection traffic lights."
Pomenuta zamjena za tranzistor "BC 308C" je pogresna.
Znaci, tranzistor "2N3904" u ponudjenoj semi ne treba koristiti (radi se o
tranzistoru NPN tipa, a treba PNP).
"BC 308C" je PNP tipa.
Izvinjavam se zbog greske.
