Mhm..I just put 120 ohms on there, and I still got a steady 4.95audioguru said:The resistor in series with the LED limits its current and adjusts its brightness.
120 ohms makes it very bright.
150 to 220 ohms makes it not so bright.
270 to 1000 ohms makes it dimmer.
1.5k to 10k ohms makes it very dim.
15k to 100k ohms makes it extremely dim.
I was also wondering, lets say you put 270 ohms on there, will it take less battery, like..would my voltage go up to 4.97 mabye?
