Hi im not really good at circuit design so i would like somebody to helpme please,

I HAENT GOT A CLUE WHERE TO START

 

hi nirvana

just saw your other post asking how a transistor works. now you're asking for a security camera circuit diagram. are you gonna make this circuit? likewise the infrared TX/RX, there are loads of circuit design in the net. just do a google search.
what's a pressure sensor linked to a PLC. :huh:
