How wonderful your day will be if you wake up from the superb melody of birds. Goodness dear! Getting up in the morning with the chirping and melodious singing of birds, what else do you need on your holiday… let’s ease into our morning with a delightful morning birds chorus sound.
This is an extremely intriguing DIY project of an automatic bird sound generator utilizing 555 ICs. The circuit will automatically produce a foul sound when the sun rises or any light falls on the surface of the LDR. The circuit can be utilized as a morning or light enacted ring or as a fun and enjoyment project.
The loudness of sound relies upon the circuit’s working voltage. At high voltage, the sound will be high and at low voltage, it will be low.

Circuit Diagram
Circuit Operation
The circuit was constructed by utilizing four 555 clock timer ICs, and every one of them is playing out an alternate role in the circuit. You can likewise utilize two NE556 clock ICs in place of four 555 timers. The light affectability of the circuit can be balanced with a 20K variable resistor. The speed of the bird’s chorus can be balanced with the 10K variable resistor. By modifying the 50K variable resistor you can set the ideal sound of the birds.
An 8 ohms 0.2-watt speaker utilizes the output of the circuit. You can likewise utilize other wattage 8 ohms speakers like 0.5-watt, 1-watt, 2 watts, and so forth. The working voltage of the circuit is 5V to 12V DC.
Applications and Uses
- It can use as a charming morning alarm bell
- It is also applicable in light-sensitive areas as an emergency alarm
