This is the LED Sequencer / LED Chaser Kit.  This is a neat circuit that lights up 10 LEDs in sequence. There are a bunch of youtube videos out there showing this same circuit. The circuit includes an adjustment for speeding up or slowing down the LEDs. Use this in a bunch of different places. You can remote the LEDs to get your own special effects. Try putting in different colors of LEDs for even greater effects. This kit will come with a set of 10 LEDs.The PCB is double-sided, plated thru-hole, 1.50" long x 3.00" wide made of .062" FR-4 epoxy glass. It has green Solder Mask (LPI) on both sides with white Silk Screen on the Top side.  It includes 4 mounting holes.This kit does not include the tools you will need to assemble the circuit. You will need tools such as a soldering iron, solder, wire cutters, etc.
