I want a circuit without LEDs to drive the buzzer with dual tone.There are a lot of "YouTube circuits" that use color changing LEDs to trigger things as they cycle.

Yes, its a general 12v BuzzerYou need a buzzer that can generate a dual tone.
Do you have a buzzer?
You could drive a small speaker with a 555 astable oscillator that can be configured to generate more than one tone.
Not likely.If there is a possibility to control the tone of the same buzzer by using an external circuit
Any tone other than general beep tone.Not likely.
What is the buzzer you want to use.
I want to go with an alarm circuit. I have that circuit and I just want to change the general beep sound buzzer at the output to get other tone (or dual tone ). I think I'm clear now.@rafiec14 this thread seems to be going in circles. Which type of circuit do you want to go with and what "buzzer" do you have access to?
It is a water level indicator circuit in which I'm using a relay to drive the buzzer.Thank you. It is getting clearer. What circuit is that?
