How to make a Featured product slider in Joomla?[MASTER]

[Sismis98]

I'am not using any fancy e-comerence plugins or extensions like VirtueMart or something like that! Iam using the Helix 3 Framework

So i want to make a featured product slider or at least a featured article slider , i want to show my products in slider that show: 1.Their name 2. The price 3. A BUY BUTTON.

It should look like the product slider of this demo site page( The one with more articles, not the big one)
