The post Sound Generator with IC 555 first appeared on Electronic Schematic Diagram.]]> This is a sound generator based on general purpose timer IC 555. A flip-flop circuit is included, so this circuit will give sound output and blinking LED.? There are 2 modules in this circuit that are flip-flop / LED flasher module and sound generator circuit modules which combined in one schematic diagram. This is a simple project for beginner which can be seen and can be heard.
