LED series resistor calculator
These calculators work out the values for an LED current limiting resistor |
|
LED calculator:
current limiting resistor value DO NOT use LEDS without a current
limiting resistor in series with the LED. The forward voltage rating is
TYPICAL and can vary from part to part, so while some LEDS may work fine
just connected to a battery of the proper voltage, others will be overdriven
and be destroyed |
