Today in this article we are going to generate a pulse using a 555 Timer IC. The circuit can be used with any project, which requires positive pulses. An LED is used at the output of the IC to show the visual indication of the output pulses.
The heart of the circuit is a famous 555 IC that is wired as an astable multivibrator here. The output frequency of pulses can be adjusted with a 100K variable resistor. A 100K pot can also be used in the place of a 100K resistor to adjust the circuit smoothly. The pulse frequency also depends on R1 and C1. The circuit can be operated from any voltage from 5 to 15 volt DC.
