Relatively cheap and pretty darn easy-to-assemble step lights made out of LEDs.
Glue gun and glue sticks
Soldering gun and solder
Felt or Thick fabric that matched the carpet on my existing steps
5mm UltraBright LEDs, color: Pure White with clear lens (3 per step light)
9v Battery (1 per step light)
9v Battery 'snap on' terminal leads (1 per step light)
Sub-mini Slide Switch (1 per step light)
Step 1: Soldering the LEDs
I chose to use 3, 5mm LEDs and 1, 9v battery so that I wouldn't have to worry about any math involving resistors. Please note that you may have to get into the math end of LEDs and their resistors if you choose to use a different combo. This was my first LED project, I wanted to keep it relatively simple.
If you're like me, you might find yourself wanting to 'play around' with the little LEDs. Try to avoid 'testing' the LEDs until they are soldered together, and then only touch the leads from the battery to the end of at least two LEDs soldered together. 'Testing' one LED can cause it to burn out from being overloaded. While you are able to light 2 LEDs as opposed to 3 with the 9v, I found the amount of light they gave off to be a little too bright for what I was going for.
To start off the step light:
I wired the LEDs in a series. This meant soldering the positive end of one LED to the negative end of the next led, then soldering the positive end of the second LED to the negative end of the third LED.
If you're not sure which little leg is the positive or the negative, don't worry. If you look closely at the two little, metal tips inside of the LED you'll see that one is larger. You want the leg coming out of the larger metal tip to be soldered to the leg of the next LED which leads up to the smaller metal tip. Once you have three LEDs soldered in a row, set it aside.
