awesome

awesome tutorial !

@blizzard249 for 1,5V u need another 1,5V because LED wont work on 1,5V
-
@justvisiblesilence so what if you have a 12v supply, what resistor would you use?
also, if you had 2 LED's connected inline, would the first one waste some of the power before it got to the second?
-
if you had 25 LEDS in series, would it be hard to fit a dimer to the setup?
-
Excellent. Thank you
-
good video.
-
on, off, on, off. lol make enough of them and you have a computer.
-
will the use of resistors make the energy of a battery last longer?
-
You can light some LEDs with a low amount of only 1.5v and not all leds light at 2v the most common ones i use are super bright and they take 3v to light, 2v is to low and they dont light, so dont tell some one that they need to increase the voltage if they dont need to.

what resistor do u use for a 1.5V?
blizzard249 1 year ago
@blizzard249 1.5V is insufficient to light up a typical led. An LED requires 2V to light up.
One AA battery voltage is too low (1.5V). Two AA battery is too high (3V). That is why we need a suitable resistor to bring it down to the LED's operating voltage of 2V.

does it actually matter where you put the resistor?

no it does not matter
