The flashing is thanks to LEDs with a built-in, integrated flashing circuit and the nasty noise comes from a piezoelectric buzzer — both are available from electronics stores that sell ordinary LEDs ...

Just go back over your circuit to see if you can find a mishap, and do check that the led is functional. By the way, you can get sound effects as well out of a LM3909, so persevere! Report comment ...

[youtube= Mad Scientist Labs brings us this easy to make LED blinking circuit. The idea is to put a LED in series with a small blinking incandescent bulb from a string of Christmas lights. The bulb… ...
