Fabulous Geoff, that was really useful information and will certainly help me, especially the app, oh and would a variable resistor work so you can manually adjust the brightness without swapping out resistors?
Hi Mark, Cannot see why not, after all a variable resistor would only vary the resistance. However, Say that you needed a 470 ohm resistor to let you use the LED on 12V. You would still fit that resistor and then wire the variable resistor in series and use a value of about 330 ohm. That would dim the LED from its highest brightness. I have not got any variable resistors to hand otherwise I would make up a circuit on my breadboard and try it. Hope that helps, Geoff.
Very nice “how to” Geoff, I use SMD’s in my emergency and utility vehicles, which fit nicely but terrible to hold on to when installing them. I will be using Potentiometer’s when I do my street lighting etc, very handy devices for controlling the amount of light. Can I ask what the App is you mentioned?...Simon
At last someone who explained resistors required for leds ....I’ve just used what came with leds or just used 1k with everything some are a bit dim I always wire in parallel seems to work ....thanks for the ideas and link for those smd lights ......regards Fred ps Geoff what was the app you use ?
Hi Fred, the App is EE Toolkit on the App Store for iOS, it’s free but for the Pro version it’s 6.99 but that dies unlock further features. It is available on Android and I checked earlier and there are loads of Apps very much the same. Glad you found it helpful as that is really the intention of the video. Regards Geoff
Great how to video , I use LED's to light my buildings as well .......Peter
Cheers Peter glad it was ok
Good stuff Geoff, many thanks.
Cheers
Very helpful. Thanks for taking the time to make this. All the best....Tom
Cheer Tom
Nice video !
Cheers

The app is EE Toolkit on iOS App Store but similar is available on play store for Android.
