DIY Strobe Light with Adjustable Frequency: Troubleshooting Tips

[bengaliblurr7]

I'm trying to build a strobe light with an adjustable frequency. I have 1.5V, 9V batteries,1 micro farad, 10 micro farad, 160 micro farad capacitors, 500k ohm volume control, 25 ohm Rheostat, breadboard and diodes. I put the battery in series with the capacitor and volume control/Rheostat in series and put a LED in parallel, but I'm not getting any flash from the LED. Any comments on what I'm doing wrong?

What you are doing wrong is not having a plan. When you build a circuit you need to work it on paper first, not just start connecting components and trying out if it works.
