For a party we were about to have I wanted a cool light display to use with my new Xmas present - an Arduino Uno. Having looked at the LED matrix's here I wanted a bigger one that I could hang on the balcony.
I also wanted it to interact with music and flash at different sound levels and have a keypad to select which animation to run.
Thus I came up with this one using some spare Xmas lights I had already butchered for some outside art projects. I also wanted it to look arty, hence the use of copper wire for inside the frame.
Before we start on the construction I will go through some of the theory behind the matrix.
Please Note : I didn't use resistors between the matrix connecting wires and the Arduino. You should really use them to limit the current to the LED's and also avoid damaging the Arduino. If you don't use them then that's at your own risk
