GREAT! just edit a little more carefully…by the way: there is no such thing as a condensator. Its just a condenser, or a capacitor…:) GREAT WORK!

Hi dear its me kaleemullah nizamani and i want to help u dear you have said that three step
but there is not a three step.. in ur last sentance u have said that 3 step one by one so first of
all you have to devide 1000 by 3 u wil got 333.33 like some thing that so actully ur step will be
about 333… and i gona share with u some about that how to calculate a resistor for led using
any kind of voltage….. you have to apply this formula
R = (Vs-Vl)/I
R mean Resistor which u wana Need
Vs mean voltage of supply
Vl mean Led required voltage
I mean Led required current
I hope Now u can run led on any voltage
By using This Formula.

If i have More then 1000 LED and I want to display in three Step so How will i connect and what will be the register value and the voltage used. but that should be in 3 step one by one.
Thanking you
