DIY FYI: Using a MAX7219 with an LED Matrix

Recently I've been playing around with an LED Matrix and controlling it with a MAX7219 LED driver. This video is a bit of a rant with some tips and tricks about getting started with the MAX7219 since I struggled a bit in getting the circuit hooked up properly when I was getting started.
