A monostable multivibrator is a timing circuit that produces a single output pulse when triggered. Using the 555 Timer IC in monostable mode, this project aims to design and simulate a circuit that ...

LED chaser lights (or) sequential LED flasher circuit on a breadboard using 555 timer + 4017 IC and a few other components. The LED’s chasing rate can be adjusted using a potentiometer in place of 47K ...

This motion detector alarm can detect a moving person from a distance of 1 meter. It uses a dual IR Transmitter-Receiver module HOA1405. When the sensor detects the reflected IR rays, alarm will sound ...
