Why do I need a resistor when using LEDs on an Uno?

But it's really about learning to design things you can be confident will continue to work.

Why do we use resistors? [The real quick reasons]

It's true that you cannot get more than 30mA with a 166 Ohm resistor connected in series.

Why do we use resistors? [The real quick reasons]

To be safe we use a 120, or better, 150 Ohm resistor.

Well I'll do some more research on rechargeable batteries.

When to use a resistor with an LED (and why)

To handle this problem a negative feedback resistor R2 in the above figure is introduced to decrease the gain to practical limits.

Why do I need a resistor when using LEDs on an Uno?

i always though that for a 1 watt or bigger led ie led 3 watt star well i was one this led calculator site that shows you what resistor to use and i typed in the info for a 3 watt led 3.

led driver/resistor question

Also, What happens when you put a resistor in a circuit? 2v then it's gonna be a lot dimmer with the engine off and really dim if we wanna use up all the batt's capacity.

led driver/resistor question

7 is not 3 Volts as 2 AA cells can deliver, but close enough for now.

Why do I need a resistor when using LEDs on an Uno?

Is that because there was no load.

Why is it necessary to use a resistor in series with an LED?

But can we do five in series with a 9 V battery? not everyone is easily math inclined! You have to take a closer look at specs to get an idea on how it will work out.
