hello , i want to interfaceing a 12v relay with pic microcontroller...
i need 6 realyz for switching 6 different comportment,
so for that purpose i need 6 diffenet transister for driving relay?
(as in figure npn transistor acting as switch and provide relay for operate)
isn't it only a simple circuit which can drive 6 diffirent relays rather than six npn transistors..... and huge repeated circuit.?
other method for interfacing relay with micro controller will be appreciate.....
