Is it possible to run to multiple LED strips at the same time from different digital pins? Making the different LED strips doing different things, or does the arduino card only focus on on pin at the time?
Search for a ropic named "doing several things at the same time".
In reality the Uno will focus on one pin at a time, checking that pin upwards of a million times a second. You may not notice that the Uno is checking several pins millions of times a second.
Find the run several things at the same time demo that uses millis().
Yes.
There are different kinds of LED strips and with addressable strips such as "NeoPixels" "DotStars" you can individually control each LED. And, that only takes one or two output pins (and virtually no additional hardware).
The Arduino can't directly power more than a couple of LEDs so "regular" LED strips require a MOSFET or transistor driver, or relay. RGB strips need 3 output pins and 3 drivers per color.
or does the arduino card only focus on on pin at the time?
Technically, the processor only does one thing at a time but it's fast enough that if you turn-on 3 strips in sequence without any delay they will appear to come-on at the same time.
If you want it to appear that multiple things are happening at once you can't use delay(). You can use multiple millis() timers. See [u]Blink Without Delay[/u] and [u]Demonstration code for several things at the same time[/u].
I see, i know the basics of some coding and soldering. I am just not sure if the arduino uno card can send different signals to the different digital outputs at the same time or at one pin at the time
Normally an Arduino output signals at one pin at the time with a delay of something like a microsecond. Using more advanced I/O some Arduinos in a sketch can set an 8 bit port making 8 signals appear at the very same time.
One way to obtain output of several bits at the very same time is using shiftregisters that get all the data and that data is made available at the same time.
So if i where to make codes for 4 induvidual led strips i would had to include all the used pins to the code? Since the uno card can only process one code at the time?
If the target is LEDs the receiver is the human eyes. Then absolute simultaneous output is not needed.
What is "one code", "two coeds"? Handling 4 LED strips is no problem for an UNO.
