Hello. So, its been sometime since I messed around with transistor circuits. I figured it'd refresh my knowledge. This is what I intended ( I have attached a schematic):
I have wired up two transistors so that an led is always on when a push button is open. I have accomplished that with PNP transistor in a simple pass configuration. Now, the second transistor, an NPN, should only light up another led when the push botton is pressed and should remain lit till the time the button is pressed.
I wired it up, but the thing is that, when i press the button, the pnp led remain on but dim and the npn led lights up. When I let the button go, the pnp leds becomes bright again and the npn led goes out (as intended).
Where am I going wrong with this basic set up? I really am amazed how easy it is to forget basic transistors circuits (for me atleast)
For image purposes, please see attached schematic. THANKS!!!!!!
EDIT: Everyone was such a great help that I ended up fixing it on my own! Thanks for all the efforts guys (sarcasm). I have attached the fixed schematic of the problem. Feel free to use it for future references
