hello,
originally, the output of my pic16f84a is used to trigger the gate of an scr to light LED's connected to a 12Vac power source. When the trigger voltage from the pic is "0" the scr is off also.
PLease help me figure out a circuit (if possible using scr also) that can do the same function as above but this time the supply is not anymore ac but 12Vdc.
As I understand the scr will remain on even after the trigger voltage is released if using 12Vdc at the anode side.
How do I connect the circuit then? or maybe another approach?
