LED Hanukkah Menorah

Step 4 Assembly

The most important thing during assembly is the polarity of the LEDs. With most designs the polarity of the LEDs would all be in the same direction for for ease of PCB design I have flipped half the them. This means you must follow the component layout graphic to ensure the flat side of the LEDs are facing the appropriate direction.

Assembly

1. Solder a jumper wire in place. I used the clipped lead from a resistor.
2. Bend the LEDs at a 90 degree angle and solder in place. Be careful of the polarity. All of the LEDs should be at the same height except the LED in the middle. This is for the light called the Shamash and should be higher than the rest.
3. Solder the 4 resistors in place.
4. Solder the momentary push button in place.
5. Solder the IC socket in place. (if you are going to solder the IC directly to the board you should probably program it first)
6. Solder the 2-pin header in place. This will be used for power. Note that I soldered mine the underside of the board so the power can be connected to the back. I will also use this to stand the menorah upright.

Tip: To solder a pin header to the underside of the board I slide the black plastic up the pins about half way, solder the pins in place, then slide the plastic back down.
