Hello everyone,
I have a doubt on the electrical resistance.

My system has three LEDs (1.2V - 10mA each)
The LED Assembly Wizard calculates a theoretical resistance of 140 Ohms
and suggests to me a resistance of 150 Ohms 5%!

Which one should I use,
the resistor 140 or 150 Ohms!?

Thanks for your attention,
greetings.

Do not worry, the ifference beetween 140 and 150 isnt that big that it can damage anything, make sure that current doent go above specifications for that diode.
