There are two main types of LED drivers available – constant current and constant voltage. Now, if your LED lights don’t have inbuilt drivers, then you need to get the driver separately.

He can’t show us the schematic, but he did share some tips on how to build an LED driver around a MAX16834 chip. As you move to higher power designs the barriers to success pile up rather quickly.

A typical LED system, Figure 1 , will have a communication interface, LEDs of various colors with each color representing a channel, some sort of intelligence, and a constant-current driver for each ...

He started with a prototype that uses a PIC 18F4580 microcontroller connected to a MAX7221 LED driver, which gave him control over some dot matrix displays to test the wiring and sample script.
