  • hot-glue gun and glue sticks
  • wire cutters
  • screw driver
  • soldering iron and solder

And materials...
  • Arduino UNO R3
  • PWM / Servo Shield
  • 2x stacking shield headers
  • 1x micro servo
  • 2x continuous rotation servo
  • #10 o-rings
  • 2x LED matrix w/I2C backpack
  • 1x NeoPixel Stick
