Hi guy actually I have made a circuit of uln2004A 16 pin IC circuit which is connected to the 12volts DC power but when I tried it on breadboard it's not working
Can anyone else say as why it didn't work

What did you expect to happen?
How do you know it is not working?
What is the circuit suppose to do? Show us your circuit.
Do you understand the meaning of open collector?

We cannot tell heads or tails from your schematic.
Where is the ULN2004?
Where is the LED?
Why should the LED light if there is one?

Where are the LEDs? What are CO2, CO3, CO4 and CO5.

If you use connection dots, you don't need to draw humps to show crossings.
