What you need

• Arduino UNO or compatible
• Power supply cable
• Multimeter
• 15mm D-shaft

Steps

1. 1. Ensure that the 15mm D-shaft is compatible with the EC12 encoder.
2. 2. Mount the EC12 encoder vertically on the base of your project.
3. 3. Connect the GND, VCC, and OUT pins of the encoder to the Arduino, respectively GND, 5V, and a digital pin.
4. 4. Load the provided Arduino code.
5. 5. Verify the output frequency from the datasheet.
6. 6. Test the encoder with a sample sketch.
7. 7. Adapt the code for your project.
8. 8. Ensure that the encoder functions correctly.

Example code

```void setup() {
  Serial.begin(9600);
  pinMode(2, INPUT); // Pin di output dell'encoder
}

void loop() {
  int value = digitalRead(2);
  Serial.println(value);
  delay(100);
}```

Mini project

Create a volume control for a speaker using the EC12 encoder as a knob.
