I am trying to learn this. I want to add LEDs to my action figures & models. But for some reason, this gives me a ridiculous amount of anxiety. I don't know why but it does.

Hello, thank you for the explanation on how to calculate the resistor needed when you want to connect an LED, I don't know much about electronics, I only do small DIY jobs on low voltage and I admit that I always have trouble knowing what resistor I should put for each LED, I'm keeping this video in my dedicated playlist because I know that by tomorrow I'll have forgotten how it's calculated and being able to find it again will allow me to come back to it in the future and find this calculation again, which will prevent me from burning out LEDs because I didn't put a resistor in. 👍😉

Very good video and I like that you go into explaining why instead of just telling us how if that makes sense lol

im just 9 years old btw but im motivated for these

AWESOME video, Thanks for sharing! I've been struggling with this when I do lighting projects. I've suffered LOTS of blown LED's from not knowing how to properly calculate the right resistors!

[jamesemery]

that's filled a gap in my knowledge cheers Lee stay safe.

[Mrnick]

Excellent video, thank you, its clear and well explained, electronics perplex me at times but this has helped me a great deal for my project!

[lorenmiller]

Extraordinarily clear. I am now a genius. Much thanks, and happy flying.

[TechNoPhobiaGirl]

Awesome! Great explanation/demonstration! Thank you so much!

[reckemroysrc]

Excellent information and very well explained. I will try to use this video to teach my boys some common knowledge of life and electronics. 👍👍😎✌👊

[adventureguy]

its interesting Flashlight makes have not upgraded to tooling for the plastic molds, they just put a led in and put in an AA C cell adapter

[raven_fpv]

Fantastic video Lee! I really enjoyed it. It is a good refresher to learn this stuff again. Electronics is so fun to mess with. Thanks for showing us this.

[mikebowers]

Really helpful for an absolute beginner (Yup that's me!)

[Glenn.J]

Do you think you could make a video on what value of a resistor do I need to mod a standard size RC servo to move more than its standard deflection?

Application: To see if we could use a cheap and cheerful standard size servo or a 9gm servo for FPV to get more panning.

Absolutely loved this video, great going.

Thanks.

I’m still a little confused on which resistor I would need, if I was to wire up 2x 12V Single LED’s to a 9V battery would I need multiple Resistors and if so how many ohms would that be? Any help would be great. Thank You

[Ormigo]

Nice video as always. I actually needed a more complex wiring diagram for example how can we connect multiple leds, let say 18 leds in a strip with a 12v battery. I don't really understand if we put more than 1 resistor how actually it works and how to calculate voltage drop etc. I was told to divide 18 leds into 3 parts of 6 leds each. The leds require 2.2 volt to light up brighter. So if I need to light them together I will need 6.6volts right?! So 12.4-6.6=5.8v/0.02= 290 ohm. So should I put a 290ohm to the beginning of the strip? Can I put 3 resistors on each part or the first solution is better?

[willswillio]

How did you find out the current the LED needs? Coz I need to know the current in order to know the resistance

[olyddiego]

great video. hope you can make e 2 way ON and OFF switch for lipo please

[ravn]

having a LED config. of around 9V with a 9V battery and a Zenner diode in parallel can act as a regulator and thus avoid using a resistor?

[RCJunky]

Is it not best practice to use a resistor on each LED in parrell to prevent circuit failure if one LED fails.
