Hello all and welcome to this Christmas tree decoration instructable.
This ornament is designed to hang on your Christmas tree just like any other decoration, but it's just that little bit more eye catching! When you turn it on it will scroll a "MERRY CHRISTMAS" message across the 8x8 display. Not interesting enough for you? Well just grab the ornament from the tree, turn it off - hold down one of the push buttons - then turn it on and now you will be presented with (possibly) the worlds smallest Christmas tree ornament video game - SANTAS SCRAMBLE!
The game is very simple, you press one of the two push buttons (on the rear of the unit) to move santa either to the left or to the right in order to avoid the oncoming obsticles (preventing him from delivering presents to the children...) the game gets faster the further you get and will tell you what level you made it to if you crash.
To return to the scrolling message, just turn it off then on without holding down a game button.
Here is a youtube video detailing the project:

First off we need to gather together all the items required to make this kit.
The kit contents:
- 1 x PIC16f677 microcontroller (SMD) - 1 x 8x8 bi-colour LED matrix - 1 x coin cell battery holder - 1 x PCB - 2 x coin cell batteries - 2 x 10k ohm resistors (SMD) - 2 x mini push buttons - 1 x mini slide switch (SMD)
You will also need:
- pickit 2 (or similar programmer) - Experience in soldering - Soldering Iron (with a small tip) - Solder - Solder wick (optional) - Flux (optional)
The solder wick is very handy when soldering surface mount components if you ever solder pads or connections together. Also, flux is unbelievably handy when you want to achieve a nice smooth finish and ease of soldering.
So fire up your soldering iron and lets get started!
