Have you ever seen or heard about Dummy Alarm? Now we are explaining you about Dummy Alarm. It is almost similar to an alarm, where as it flashes high power red LEDs for every 5 seconds. The main ...

Here is an interesting project named police car lights designed using 555 timer. This circuit simulates the police car lights by alternate flashing. This circuit simulates the police car lights by ...

Sometimes the best inspiration is limitation. The 555 timer does “one thing” — compares a voltage to a couple thresholds and outputs a signal accordingly. It’s two comparators, a voltage ladder, and a ...

In this project, I'll make a small circuit capable of blinking lights, on its output we get a digital signal that we can use ...
