Parts Express 320-291 is a 3D Color Changing LED Christmas Tree Kit that allows you to build your own three-dimensional, color-changing Christmas tree. It features 36 clear LEDs that flash multiple colors alternately, creating a festive and eye-catching holiday decoration. The kit includes three circuit boards, resistors, transistors, capacitors, and LEDs, as well as a battery box and a key switch. The finished tree measures 2.36" x 2.36" x 5.35" and can be powered by either 3 AA batteries or a 5 VDC USB power supply.
