Pull up and pull down resistors preventing false triggering 2N3904 NPN 2N3906 PNP BJTs explained

Описание к видео Pull up and pull down resistors preventing false triggering 2N3904 NPN 2N3906 PNP BJTs explained

I show how pull up and pull down resistors can help prevent false triggering of an otherwise floating input pin. I can easily get an NPN (2N3904) or PNP (2N3906) transistor to start conducting by touching a conductive area attached to the floating base pin.
