I have tried to use the site to find an answer to this, but it seems everyone that has asked questions have different variables than I am dealing with, and I can't ever seem to grasp electrical concepts or formulas. I even tried the automatic calculators, but they show only one resistor, and the articles I find here say one is required for each LED.
I wish to make two flickering LED lit panels to simulate a wood or coal burning type display that will be used in a 12 volt motorcycle system. Each panel will have five individual orange LEDs and five individual yellow LEDs, shining against a small white plastic panel. There will be two panels on one switched circuit.
The LED specs are:
- Size: 5mm
- Animation: Flickering (irregular) like artificial candles
- Source voltage (motorcycle battery): 12V
- LED Forward Voltage (Orange): 1.9V to 2.1V
- LED Forward Voltage (Yellow): 1.8v to 2.2v
- Current per LED (both colors): 20mA
I need to know the best way to wire these, (series or parallel) or and what value of resistor to use, and how many.
