Door Activated LED Lighting using Hall Effect Sensors

Step 3 Solder in the LEDs

The next step is to place the LEDs in their holes and solder them together. I found that bending the positive leads in until they touch makes soldering alot easier. I attached a wire to the positive leads, taped over them with electrical tape, and did the same for the negative leads. It also saves space if you solder one leg of a resistor to either the positive or negative leads so it doesn't have to be done on your protoboard. To connect the LED units, i drilled two holes into the side of each case, ran the casing down the wire, stripped the wire and tied together the main lines to the LED wires.

The only reason I used three separate 33 ohm resistors in each case, rather than one 10 ohm resistor is because I soldered together the first light with a 33 ohm resistor and didn't feel like desoldering anything :) .
