I now have a MAX7221 and the same 5 digit display as I posted above. Also I have one 0.1uF electrolytic condensator, and max to 100nF all sorts of ceramic condensators. Resistors I have. Can someone tell am I able now to get working MAX7221?

Well there didn't read anything about changing other electrolytic condensator to smaller ceramic/electrolytic. It just says that there must be condensators.

It tells you the size, where to put them, and why.
