Guys in this Video i will show you how you can make an Easy and helpful project : Electronic composant Tester, very useful.
you can test all Transistor Bipolar PNP and NPN
you can Test Ziner Diode and know there tension also
you can Test OPTO 4 and 2 PINs
transistor BC 547, BC 548, BC 549, BC 557, BC 558, BC 549 , BC 337, BC339
transistor 2n2222, 2n2222a, SC 904 , SC 905
Diode Ziner 3v3 3v1 5v1 4v7
