Yes. You can even have the LEDs fade from one to the next as they scan back and forth, instead of flashing on and off. You will just need 2 series resistors, 5 digital pins and 1 pwm pin. I can draw you a schematic if you need one.

That is not the way LEDs are normally characterised, you normally have a forward voltage drop at a specific current, like 3.2V @ 20mA. This is normally between 1.2V to 3.8V no higher.What you posted implies it already has a resistor built in. Can you post a link to where you got them from please?
Fortunately for the supplier, I guess lots of his customers don't know Ohm's Law.
To: email@example.comSubject: Incorrect description of eBay Item Sir,Your eBay item Pre Wired LEDs 3mm Clear 5V-12V Various Colours/Packs Prewired UK SellerHas a false description , it says:-5 - 12VDC15-20mAThis is a technical impossibility for an LED fitted with a series resistor. This has been causing confusion over on the Arduino forum.It also says:-Perfect for Arduino, ATMEL, PIC, PICAXE & Raspberry PI electronic projects If the minimum voltage is 5V then it can not be perfect for a Raspberry Pi which only provides 3.3V at its output pins.My suggestion is that it would be better if you just stated the forward voltage of the LED and the size of the series resistor, but if you do want to specify a voltage range then the current range must be correct to comply with the trades description act.I would be obliged if you were to change the description of this product to a truthful one.Mike Cook
