Hi all,
I'm relatively new to electronics and I'm trying to build an analog circuit to imbed into a Halloween prop. I want to activate a GPD2846 MP3 player with a PIR sensor using a PNP2222 transistor. The MP3 and PIR can operate from ~ 5v and the PNP2222 should be able to switch with the ~3v from the PIR output. But, it's not working. Attached is my schematic of the circuit but I'm kinda flying by the seat of my pants and I'm not sure why this doesn't work.
One thing to note is that I know the schematic lists a 5v battery power source but I'm using a 5v computer PS.
Any help would be great!!
