555 circuit Fade/flash LED
November 27, 2016 - 2:44pm

Hi,

I wish to make a model lighthouse on my 00 gauge model railway layout flash and fade the LED's.

This has fitted those 12/15 v. LED strips. I have two strips in series and wish to make them flash

but also fade. Using the 555 timer circuit as shown on the web site it uses resistors. Do I just

use this without the resistors used? Hope I get a reply. Any help appreciated.

Hi Lee,

 

We are hppy to help you but please make you question more appropriate.

Using the 555 timer circuit as shown on the web site it uses resistors

Which Timer circuit are you talking about, there are a lot of Timer circuits using 555 on our website, mention the one which you are planning to use. A circuit diagram will be of more help.

 

Thanks.

Many thanks for your reply B.Aswinth Raj

I am new to this forum and would only call myself an enthusiastic hobbyist. 

The LED strips I have used already have voltage protection within the strip.

Hope this helps.

Best Wishes,

Lee
