Transistor BC547 activating after turning on base pin even without turning on the collector pin

I'm just trying to use these transistors for logic gates

What kind of gates?

[runaway_pancake]

jim-p showed you a viable circuit in Post No.17

[jim-p]

Here is a NAND gate

AND gates

Maybe we need to start over from the beginning.
What exactly are you trying to accomplish?
How is an Arduino involved?

[ilovelectronics]

The arduino is involved by powering everything, with the 5v and gnd pins, I will show you what circuit I'm using

[jim-p]

@ilovelectronics

I will show you what circuit I'm using

I want to know what you are trying to do not what circuit you have. Everything you have shown so far isn't quite right.
