Attachments
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
