Connect the pins of rotatory encoder to the given below digital pin input of the arduino.

CLK = 3

DT = 4

SW = 2

Positive to 5v 

Ground to gnd

Connect the pins of sound sensor to the given below analog pin input of the arduino.

SENSOR_PIN A0 to analog pin 0 (A0).

Positive to 5v

Ground to gnd

Use the big gear ratio to match the low gear ratio and put the rotatory encoder in the low gear ratio.

Use the below given pin pattern to connect joystick as a manual gear box to the arduino.

Use the first pin as ground and connect it to gnd pin of arduino.

Attach all the other pins of joystick to digital pin 6, 7, 9, and 8.

Use the negative points of the button and connect to the gnd pin of the arduino.

Use the positive pin of the button to analog pins A3 and A4.

Use the positive pin of the pedal to analog pin A2.

Flash the arduino code provided in the project files and you are good to go.
