Hi to all Today's the instructable is about the FLASHING of an LED which can be

used in so many different application exp decorating , indication etc

This is very simple instructable anybody can do it.

D I Y IN 4 MINUTE COMPLETE VIDEO GUIDE STEP BY STEP

I use a 555 timer ic to generate frequency which can be tuned to

different levels of frequency by using the potentiometer

A buzzer used is optional here

PNP / NPN transistor can be connected at the output if we need to derived a bulk of LED OR Motor etc

Different electrolytic capacitors can be used to set the desired delays at

output i tested different electrolytic Capacitors in the last minutes in my video

Step 1: Hardware Required

All the hardware details including circuit diagram are given in the video description

hai! can u try do it with piezo? and how did u know what to use to light a bulb (like resistor etc? thanks!
hi miraheng you can use a piezo <br>it will work the same <br><br>for lighting a bulb at the output you need to connect a bulb 6v relay at output but this is good for lower frequency switching <br><br>but for faster switching at output we need to do something else ...like using power transistors etc
<p>First off, thank you. A well laid out Instructable. But, where is the PNP transistor you mention in the initial description? And I'm not seeing it in the &quot;Hardware Required&quot; list. I'm really new to this and last week ordered all the goodies to put something like this together, so this is timely. I don't see what I think a PNP transistor would look like used anywhere in your circuit, either. </p>
Thanks for letting me know <br><br>PNP transistor is optional here <br>if we need to derived a big load rather than LED .like motors OR many LEDs .<br>But for a single led it's optional here .<br><br>I forget to mention in my post <br>but don't worry it will be updated soon. <br><br>
<p>If you could possibly show both circuits, one with the transistor and one without, I would appreciate that. I'm getting so that I kind of understand the workings of the components, but their practical application is difficult. Thanks, again. </p>
these are two circuit one with NPN transistor and other without transistor <br>you can use any small gain transistors like <br>2n3904<br>2n2222<br>bc547 <br>these are very common <br>
if you feel any difficulty please ask <br>thanks
