555 Pulse Generator Module, How it Works

The 555 timer IC is an integrated circuit that is used in a variety of timer circuits, pulse generators and oscillator applications. The heart of the module is the 555 timer IC that is wired as an astable multivibrator, generating pulses from about 4Hz to 1.3Khz.

This circuit can be used in any project, that requires positive pulses.

To demonstrate the operation, a LED is used at the output of the IC to show the visual indication of the output pulses.

The output frequency of pulses can be adjusted using a potentiometer. The circuit can be operated from any voltage between 5 to 15 volt DC.
