Decorate for the holidays in SparkFun style with the Through-Hole Christmas Kit! This ornamental kit comes with a neatly-cut, tree-shaped PCB, adorned with super-bright green LEDs, and topped with a yellow LED. The LEDs are controlled by a pre-programmed ATtiny85 AVR, and the circuit is powered via a couple AA batteries. The included battery holder has an ON/OFF switch so you can turn the ornament off to save on battery life. This kit comes as a bag of parts, which you'll need to solder onto the tree PCB. All components are through-hole, so this is a great kit for that first-time solderer. Make sure you install everything with the correct polarity! Happy holidays, from SparkFun!
