This is a simple circuit to build a traffic signal using an IC 555 - Timer and IC CD4017 – Decade Counter. In a Traffic light there are three different color LED which are Green (Go), Yellow (Caution) and Red (Stop). Here IC 555 is used in Astable Multivibrator Mode. The timing of signal can be adjusted by varying potentiometer.

This is an easy to use fire alarm. The circuit uses an NTC as a temperature sensor. As this temperature around NTC increases its resistance decreases. A potentiometer is used to provide a reference voltage. As the temperature around NTC increases, a voltage drop occurs which drives a transistor in turn activating the buzzer & glowing the LED.
