E6B2-CWZ3E Rotary Encoder 2000P/R

Description

What it is

The E6B2-CWZ3E is an electronic component used to measure the number of rotations of a mechanical device. The encoder’s output is a digital signal that can be interpreted by a microcontroller such as Arduino to determine the angle of rotation or the rotation speed.

Features

• Model: E6B2-CWZ3E
• Pulses per rotation: 2000P/R
• Diameter: 40 mm (check the datasheet)

What it is for

The E6B2-CWZ3E rotary encoder is ideal for Arduino projects that require precise motion control, such as:

• Rotation counter for drones or robots
• Step motor control
• Measurement of the rotation angle of a device

Tutorial: How to use E6B2-CWZ3E Rotary Encoder 2000P/R

The E6B2-CWZ3E rotary encoder is a component used to measure the rotation of a device. Useful for projects requiring precise movement control, suitable for beginner and intermediate makers.

What you need

• Arduino or compatible

Steps

1. 1. Mount the encoder on your project, ensuring that the rotation is free.
2. 2. Connect the VCC pin of the encoder to the VCC of your Arduino.
3. 3. Connect the GND pin of the encoder to the GND of your Arduino.
4. 4. Connect the DO (Data Output) pin of the encoder to a digital pin of your Arduino.
5. 5. Load the provided Arduino code.
6. 6. Verify the rotation of the encoder with a sample sketch.
7. 7. Adapt the code to use the encoder as needed.
8. 8. Test your project.

Example code

```void setup() {  Serial.begin(9600);  pinMode(2, INPUT);  attachInterrupt(digitalPinToInterrupt(2), count, CHANGE);}int count = 0;void loop() {  if (digitalRead(2) == HIGH) {    count++;    Serial.println(count);  }}```

Mini project

Create a simple rotation counter for a drone or robot. In 30 minutes, you can mount the encoder, connect it, and control the rotations.

Common mistakes
