LEDs behaving erratically

[Twiggy]

Okay so I built this circuit shown and it behaves as intended. However when I add a potentiometer between the 9v battery and up the resistance the left LED stays mostly on and only briefly flashes the one on the right. In a couple of seconds however it equals out. I have tried to work this out myself but I cannot.

Please post a schematic.

its right there mate

Are both LEDs the same?

Asking for a circuit because it is not clear where you have put the pot. Re-read your post.

Although it's not possible to add a pot "between the battery" I assume he added the pot between the battery and the circuit.

I guess he joined 100k's and added the pot between battery and the junction.

 

[Twiggy]

Boncuk is correct there is simply a pot on the single wire connecting the 9v to the rest of the circuit. in my original post i meant to say "between the 9v battery" and the rest of the circuit.

Why would you put a pot there?

Again are both LEDs the same color?

 

[Twiggy]

just to see really. again both LEDs are identical, however i will assume that this would not happen if that was the case. One is a little older than the other, and has had a bit of wear and tear, but is otherwise identical.

If you disconnect one end of each 100KΩ resistor, connect these two ends together and connect them to the wiper(center contact of a pot) then connect one of the other pot terminals to the 9V battery you will be able to adjust the flash rate of the LED's
