LED Flashing Kit Tips

-If you happen to have soldered the resistors in the opposite spots, just switch the LEDs and you'll be fine. Keep the LEDs in the directions the LED in that spot should have been.

- Do not keep your soldering iron on the 555 timer chip or capacitor too long or it will burn up and not work. The current should still pass through the chip even if you've burnt it out, but the chip then doesn't do any function and you have only soldered a simple circuit. 

- If your components aren't staying mounted on the PCB (Printed Curcuit Board) when you are soldering, a small piece of Painters Tape always does the trick.
