EC11 20pints 15mm 5pins Digital Audio Encoder / Code Switch / Digital Audio Potentiometer

Description

What it is

The EC11 20pints 15mm 5pins is a digital audio encoder designed to be used with Arduino and other electronic platforms. It allows for the conversion of mechanical rotation into digital signals, which can be read and interpreted by a microcontroller.

Features

• 20pints
• Dimensions: 15mm
• 5 pin
• Type: Digital audio encoder

What it is for

The EC11 encoder is ideal for applications requiring precise and digital control of a mechanical action. Example usage: creating an automatic valve opening system with a button. The encoder can be connected to a button and a valve, and an Arduino sketch can be used to control the valve’s state based on the digital signal received from the encoder.

What you need

• Arduino or compatible microcontroller
• Connection cable
• Valve or gate to control

Steps

1. 1. Assemble the valve or door in the closed position.
2. 2. Connect the GND pin of the encoder to the GND of the microcontroller.
3. 3. Connect the VCC pin of the encoder to the VCC of the microcontroller.
4. 4. Connect pin 1 (SW) to a digital pin of the microcontroller.
5. 5. Connect pin 2 (GND) to GND.
6. 6. Connect pin 3 (VCC) to VCC.
7. 7. Connect pin 4 (SW) to an analog pin of the microcontroller.
8. 8. Connect pin 5 (GND) to GND.

Example code

```void setup() {
  pinMode(2, OUTPUT);
  pinMode(A0, INPUT);
}

void loop() {
  if (digitalRead(2) == HIGH) {
    int val = analogRead(A0);
    if (val > 512) {
      Serial.println("Aperto");
    } else {
      Serial.println("Chiuso");
    }
  }
}```
