Multiple Led Single Resistor at Lea Cheney blog

Multiple Led Single Resistor. I'm using 3ma led's and 2.2k resistors. Only one led is on at a time. You can do that safely if: One of the first things students are taught about leds is that each led in a parallel circuit must have its own resistor. I'd like to attach one end of the leds to individual digital output pins while the other ends are. This instructable will show you how to calculate the required values to connect multiple leds with a single resistor vice an individual resistor per led. Use one resistor per led in this sort of application. The main reason is because you can't safely connect diodes in parallel. The only way you can (simply) run multiple leds using a single resistor is if they are all wired in series. Even then you should only wire leds that require the same current and also ensure the sum. So when we use one resistor, we have a current limit for the whole diode section. This often isn't specified by 5 v is generally quite. The voltage of the circuit is less than the maximum reverse voltage of the leds.
