A real bird sound generator is an electronic circuit that makes the exact sound of a bird. It is a simple circuit that can be used in a wide variety of projects that need incredible sound bells. The output of this circuit is so fine that the person listening would never be able to distinguish between the real bird and the sound generated by this circuit.
In this circuit, the bird’s chirping is made with a core element, i.e. 555 IC, which is specifically used to generate oscillations. However, this core element is used in multiple numbers to make the circuit easy and effective. Thus, by using three 555 timer ICs, you will be able to perform a variety of difficult tasks easily.

Bird Sound Generator Circuit
Working Explanation
The signal generates from a battery. A 10k variable resistor is connected to the 5V-12V DC battery to control the chirping sound. The circuit uses three 555 timer ICs for separate functions. These ICs connect to different values of resistors and capacitors for different outputs at different levels. In the end, the circuit connects to an 8 ohm, 0.2-watt speaker for the final output i.e. the sound of a bird.
Applications & Uses
- This circuit is generally used in doorbells and toys.
