Readme

This small candy cane shaped board contains a 16 led array and a push button, all controlled by TI's low power MSP430G2221IPW14 16bit 14 pin micro-controller. The board is powered by a small CR1025 coin cell and it may be re-programmed using a small 1.27mm pitch connector that fits the Launchpad value line dev board. To get that real Christmas look it should be fabricated with white soldermask and red silkscreen!
