Supplies

8x 220 ohm resistors

8x Leds of your choice

19x cables

1x breadboard

1x Arduino Uno

1x sound sensor

Step 1: Resistors

Connect the 220 ohm resisors starting at pin 30 and finish at pin 56 in order crossing the middle of the breadboard as shown. leave a 2 pin gap between each resistor.

Step 2: Wires


firstly connect the wire on pin 56 from the breadboard on -9 of the arduino uno.

next connect the wire on pin 53 of the breadboard on 8 on the arduino uno .

then connect the wire from pin 49 of the breadboard to pin 7 of the arduino uno.

then connect the wire of the breadboard on pin 46 to pin 6 of the arduino uno

then connect the wire of the breadboard on pin 42 to pin 5 of the arduino uno

then connect the wire of the breadboard on pin 37 to pin 4 of the arduino uno

afterwards connect the wire of the breadboard on pin 33 to pin 3 of the arduino uno

lastly the wire of the breadboard on pin 30 to pin 2 on the arduino uno

Step 3: Leds

After connect the leds on the opposite side of the wires as shown above.the leds have to be at the same as shown above. the leds can be any color you want.

now connect the first led on pin 4 and 5,

now connect the first led on pin 7 and 8

now connect the first led on pin 10 and 11

now connect the first led on pin 13 and 14

now connect the first led on pin 16 and 17

now connect the first led on pin 19 and 20

now connect the first led on pin 22 and 23

now connect the first led on pin 25 and 26

Step 4: Wires

use 7 wires to connect the leds together on pin

5 until 8

8 until 11

11 until 14

14 until 17

17 until 20

20 until 23

23 until 26

Step 5: Sound Sensor

connect vcc from the sound sensor to 5v of the Arduino uno

the gnd from the sound sensor to the gnd of the arduino uno

and the out of the sound sensor to A0 of the Arduino uno.


Step 6: Wire

afterwards connect a wire to pin 25 next to the led then connect it to to the gnd of the arduino uno

Step 7:

lastly uploud the code on arduino which you can code yourself or find a code on the internet. the arduino app is called Arduino IDE
