Hello all.
I have modified a LED audio VU meter **broken link removed**to have 10 LEDs shine at once for every 1 LED on the meter. It is 10 LEDs long so there are 100 in total (the kit on the link has 12 leds but I am only using the middle 10). I have made a prototype with 10x red 12v LEDs running in parallel off every point, and it works well but probably could be brighter. At the moment I am only using a 9 volt supply too, I plan on using a 12v one.
It is my aim to have 4 of these meters, Red, Yellow, Green and White. I was initially just going to purchase another 300 12v LEDS and make up the other 3 but now I am thinking that I can use lesser voltage LEDs with a resistor (muc cheaper, especially for white leds). If I can get better results this way I may re-do the red 12 volt ones. Also, is there a benefit to running them in series? They seem to work well in parallel but it has been suggested to me to run them in series.
My question in a nut shell:
What is the best way to wire 10 leds to every one of the leds on **broken link removed**.
any help much appreciated
