Chanukah is coming soon! So I thought it would be a great idea to make a project relating to the holiday. I made this cool Chanukah Menorah with an Arduino that plays a different song each time you change the night by pressing the button. The LEDs flicker similar to a flame on a candle. I found the songs for the Menorah by finding MIDI files of the song and using an online tool to convert it to an Arduino tone code.

Step 1: Parts/Materials

Switch to each picture to see what part it is. Hover your mouse over each object.

Step 2: Cut the LEDs

Cut 8 of the 9 LEDs about half way leaving one LED uncut. The uncut LED be the Shamash (The taller candle in the middle).

Step 3: Put the LEDs Into the Breadboard

Next, put the LEDs into the breadboard and place them equidistance from each other(every LED should have the same amount of distance between each other). I placed each LED 2 pins/holes between each other. Each side should have 4 LEDs with the Shamash (tallest LED) In the middle separating the two sides.

Step 4: Place a Short Piece of Wire Connecting Each Ground Pin to the Ground Bar

Place a short piece of wire connecting each ground pin of every LED to the Ground Bar (Usually marked in Blue).

Step 5: Connect the Ground and Positive Rails to 5v (5 Volts) and GND (Ground)

Take two wires and connect the bar marked in red to the 5v Pin and the Ground rail to the ground pin (GND) on the Arduino.

Step 6: Connect Each LED to Their Proper Pin

Connect each LED to their specific numbered pin on the Arduino. This time your connecting the LED's other pin (NOT GROUND) to the corresponding pins on the Arduino. *NOTE as you go from right to left the pin numbers decrease. The first LED (It starts on the right side) goes to pin 13 the next to pin 12, then 11, 10 ,9 8, 7, 6 and 5 should be the last pin for the last LED (All the way at the end of the left side) Your LED Menorah should look something like the last image of this step with all of the wires connected up.

Step 7: Next Place the Button on the Breadboard

Next, place the button on the breadboard making sure that one side of the pins is on one side of the breadboard while the other pins are on the other side of it.

Step 8: Connect a Resistor Up to the Button

Connect a resistor up to the lower right side of the button with the other leg of the resistor going to another column on the breadboard.

Step 9: Connect the Resistor to 5v and the Button to Ground

Take a wire (The red wire in the image) and connect it to the same column as the other side of the resistor. Connect the other side of that wire (The red wire in the image) to the 5v rail (The red one). Then take another wire (It is the black wire in the photo) and connect it to the top left side of the button and connect the other side of that wire to the ground rail (The blue one).
